Description

Technical Field

[0001] This invention relates to the field of ambient lighting technology, and more specifically, to a color-changing ambient lighting system based on ambient air quality detection. Background Technology

[0002] As people's demands for quality of life and health increase, indoor air quality monitoring has gradually become a focus of attention. Traditional air quality testing equipment mostly presents test results on digital displays, requiring users to actively view them. Moreover, professional parameters (such as PM2.5 concentration and formaldehyde content) are not intuitive enough for ordinary users, making it difficult to quickly perceive environmental risks. Meanwhile, colorful ambient lights, as a new type of lighting device, are widely used in homes, offices, and other scenarios because they can create scene atmospheres through rich colors and dynamic effects. However, most existing ambient lights only have decorative functions and are not integrated with environmental monitoring, resulting in limited functionality.

[0003] Humidity in the air is a core factor affecting detection accuracy. In traditional systems, gas sensors such as formaldehyde and TVOC are directly exposed to the environment. When the humidity exceeds 60%RH, water molecules easily form a water film on the surface of the sensor electrodes, hindering the contact between the target gas and the electrodes, resulting in lower detection values. Moreover, under high humidity conditions, the reading of formaldehyde sensors may be 30% higher, which seriously affects the reliability of the data. Although humidity control components have been designed to address the above problems, most current humidity control components use a single moisture-absorbing material and have no regeneration function. After the material becomes saturated, it needs to be replaced frequently, resulting in high maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a color-changing ambient light based on ambient air quality detection and its control system, so as to solve the problems mentioned in the background art.

[0005] A color-changing ambient light based on ambient air quality detection includes a detection chamber, an ambient light connected to the upper end of the detection chamber, an air inlet pipe connected to the front end of the detection chamber, a filter connected to the front end of the air inlet pipe away from the detection chamber, and a humidity control component connected to the end of the air inlet pipe facing the middle of the detection chamber. The humidity control component includes an electric telescopic rod, one end of which is connected to a control component. The end of the control component away from the air inlet pipe is connected to a detection chamber. Rectangular connecting blocks are connected to the upper and lower sides of the end of the detection chamber facing the air inlet pipe. Several louvers are connected to the end of the detection chamber away from the air inlet pipe. Several sensors are installed in the inner cavity of the detection chamber. The louvers are installed at the front end of the detection chamber.

[0006] Preferably, the control component includes a control frame, the inner cavity of the control frame is connected to a plurality of moisture-absorbing silicone, and the control frame has first rectangular grooves on the upper and lower sides of the end facing the detection cavity. The hygroscopic silica gel has a porous structure and is made of hydrophobically modified silica gel with non-polar groups coated on its surface, thereby reducing its adsorption capacity for formaldehyde and TVOC, and retaining only the adsorption of water molecules.

[0007] Preferably, a second rectangular groove is provided in the inner cavity of the detection chamber, and drying chambers are connected to both sides of the end of the detection chamber facing the air inlet pipe. An air outlet is connected to the end of the second rectangular groove away from the drying chamber, and an air outlet is provided at the end of the air outlet away from the second rectangular groove. The air outlet is located on the side of the detection chamber.

[0008] Preferably, the control component is installed in the inner cavity of the second rectangular slide, the rectangular connecting block is installed in the inner cavity of the first rectangular slide, and a miniature fan is installed in the inner cavity of the air inlet pipe.

[0009] Preferably, a control system for a color-changing ambient light based on ambient air quality detection is provided, wherein the color-changing ambient light and its control system based on ambient air quality detection include a humidity control module, a sensor module, a data processing module, a control module, and an ambient light module. The humidity control module is used to control the humidity of the gas being detected. The sensor module, based on the humidity control module, is used to collect PM2.5 concentration, formaldehyde concentration and TVOC concentration in ambient air; The data processing unit, based on the sensor module, is used to filter, perform dual calibration, and conduct multi-parameter fusion analysis on the collected parameters to obtain the air quality level. In addition, the data processing unit will periodically calibrate the sensor drift problem through a dual calibration mechanism. The control module, based on the data processing module, is used to generate lighting control commands according to the air quality level. The ambient light module, based on the control module, is used to make the ambient light present the corresponding color, brightness and dynamic effects according to the light control command; The temperature control module ensures that the humidity content of the gas being detected is less than 50%. At this temperature, the gas enters the detection chamber through the hygroscopic silica gel. As the gas continuously flows into the detection chamber, it exerts a thrust on the louvers, causing them to rotate and allowing the gas to be transported to the outside. As the gas passes through the detection chamber, various sensors collect the concentrations of PM2.5, formaldehyde, and TVOC in the ambient air. These data are then transmitted to the data processing unit via the sensor module. The data processing unit filters, performs dual calibration, and conducts multi-parameter fusion analysis on the collected parameters to obtain the air quality level. The control module then generates lighting control commands based on the air quality level, and the ambient light module adjusts the color, brightness, and dynamic effects of the ambient lights according to these commands.

[0010] Preferably, the data processing module includes a seasonal threshold adjustment module, a hazard level module, and a dual calibration mechanism module; The seasonal threshold adjustment module is used to analyze the air quality characteristics of different seasons and preset a threshold correction table in the control unit. Then, it automatically identifies the season through a real-time clock, triggers the threshold switching, and the threshold correction table is as follows: Winter (November to February of the following year): PM2.5 "light pollution" threshold from 75 μg / m³ 3 Relaxed to 90 μg / m 3 This reduces frequent color changes caused by short-term fluctuations; Summer (June-August): The threshold for "excellent" formaldehyde levels is 0.08 mg / m³. 3 Tightened to 0.07 mg / m 3 Early warning of the risk of formaldehyde volatilization under high temperatures; The hazard level module is used to determine the hazard level of pollutants based on surveyed medical data: formaldehyde (carcinogenic) > PM2.5 (respiratory damage) > TVOC (irritant), and priority judgment logic is written into the control unit. When multiple parameter results conflict, the lights are forced to be driven by the level of the higher priority parameter. The air quality levels use "internationally recognized safety colors" and provide color explanation diagrams in the app, while also supporting user-defined colors.

[0011] Preferably, the dual calibration mechanism module includes an automatic calibration module and a user calibration module; The automatic calibration module is used to write a time-triggered function into the device firmware, which starts calibration every 30 days from 2 to 4 a.m. It compares the current sensor reading with the "clean air reference value" stored at the factory. If the deviation exceeds 15%, it automatically calls the compensation coefficient matrix for correction. The user calibration module is used to develop a "one-click calibration" entry in the mobile APP, guiding users to trigger it after opening windows for ventilation for 1 hour. Then the system sets the detection value at this time as the new benchmark and reverse-calculates the compensation coefficient to finally calibrate the sensor drift problem. In the automatic calibration mechanism, the time-triggered function is used to precisely control the timing of the sensor's automatic calibration (2-4 AM every 30 days). Its core is to establish the trigger condition through the time parameters (year, month, day, hour, minute) of the real-time clock (RTC) module. The specific formula and logic are as follows: The mathematical expression for the time-triggered function: Trigger(t) = \begin{cases}1&\text{calibration condition satisfied}\\0&\text{calibration condition not satisfied}\end{cases} Where t is the set of real-time time parameters, i.e., t={Y, M, D, H, Min} (Y=year, M=month, D=day, H=hour, Min=minute). The function returns a value of "1" to indicate that calibration is triggered, and "0" to indicate that calibration is not triggered. The core of the trigger function is to ensure that the calibration is performed within a window period of "every 30 days + 2-4 AM" through multi-layered condition checks. The specific conditions are as follows: Periodic conditions (every 30 days) Starting from the device's first power-on time (t_0 = {Y_0, M_0, D_0, 0, 0}), calculate the number of days between the current time and the starting point: ΔD =(Y-Y_0)×365+(M-M_0)×30+(D-D_0) When ΔD\mod30=0, the 30-day period condition is satisfied (\mod is the modulo operation). Time window conditions (2-4 AM) The hours (H) and minutes (Min) of the real-time time must meet the following requirements: 2≤H<4 and 0≤Min<60 The calibration is triggered only during the window period from 2:00:00 to 3:59:59 every day.

[0012] Preferably, the humidity detection module is used to detect the humidity of the hygroscopic silica gel. If the humidity exceeds 50%, the processing unit will activate the electric telescopic rod to retract, thereby aligning the hygroscopic silica gel connected to one end of the control frame with the drying chamber, and allowing the drying chamber to dry the hygroscopic silica gel until the hygroscopic silica gel connected to one end of the control frame is completely dried, at which point the drying chamber will stop. At this time, if the humidity of the hygroscopic silica gel connected to the other end of the control frame is detected to exceed a certain percentage, the electric telescopic rod will be activated to extend, aligning the hygroscopic silica gel connected to the other end of the control frame with the drying chamber, and allowing it to dry.

[0013] Compared with the prior art, the advantages of this invention are: 1) In this invention, the hydrophobic modified silica gel used in the control component is modified with non-polar groups on its surface, which adsorbs only water molecules in the air and does not adsorb target detection gases such as formaldehyde and TVOC. This solves the problem of "non-specific adsorption" of detection gases by traditional moisture-absorbing materials. At the same time, this structure can stably control the humidity of the air entering the detection chamber below 50%RH, thereby improving the accuracy of the collected data. Moreover, the humidity control component, through the cooperation of the electric telescopic rod and the drying chamber, realizes the automatic switching and drying regeneration of the moisture-absorbing silica gel, thereby reducing maintenance costs and avoiding monitoring interruptions caused by frequent downtime maintenance.

[0014] 2) In this invention, the hazard level module sorts the health risks according to the priority of "formaldehyde > PM2.5 > TVOC", which solves the problem of logical confusion when multiple parameters conflict. At the same time, the seasonal threshold adjustment module dynamically switches the threshold according to the air quality characteristics of winter and summer. In this way, the priority of health risks and the seasonal threshold adjustment can avoid the impact of seasonal differences on air quality, and also avoid the situation of frequent lighting or delayed warnings due to fixed threshold settings.

[0015] 3) In this invention, a closed-loop correction is formed through a dual calibration mechanism: automatic calibration is triggered every 30 days at dawn, and the deviation is corrected by comparing with the "clean air reference value"; and users can calibrate with one click through the APP. In this way, the authenticity of the detection value can be improved by the dual dynamic calibration mechanism of the automatic calibration module and the user calibration module, thereby improving the accuracy of the data collected by the sensor, and allowing users to make timely corrections when they find data abnormalities.

[0018] Example: Please refer to Figure 1 and Figure 2 A color-changing ambient light based on ambient air quality detection includes a detection chamber 1, an ambient light 2 connected to the upper end of the detection chamber 1, an air inlet pipe 3 connected to the front end of the detection chamber 1, a filter 4 connected to the front end of the air inlet pipe 3 away from the detection chamber 1, and a humidity control component 5 connected to the end of the air inlet pipe 3 facing the middle of the detection chamber 1. Please see Figure 3 The humidity control component 5 includes an electric telescopic rod 501. One end of the electric telescopic rod 501 is connected to a control component 502. The end of the control component 502 away from the air inlet pipe 3 is connected to a detection chamber 503. Rectangular connecting blocks 504 are connected to the upper and lower sides of the end of the detection chamber 503 facing the air inlet pipe 3. Several louvers 505 are connected to the end of the detection chamber 503 away from the air inlet pipe 3. Several sensors are installed in the inner cavity of the detection chamber 503. The louvers 505 are installed at the front end of the detection chamber 1.

[0019] Please see Figure 4 The control component 502 includes a control frame 506, the inner cavity of the control frame 506 is connected to a plurality of moisture-absorbing silicone 507, and the control frame 506 has a first rectangular groove 508 on the upper and lower sides of the end facing the detection cavity 503. The hygroscopic silica gel 507 has a porous structure and is made of hydrophobically modified silica gel. Its surface is coated with non-polar groups, which reduces its adsorption capacity for formaldehyde and TVOC, and retains only the adsorption of water molecules.

[0020] Please see Figure 1 and Figure 2 The inner cavity of the detection chamber 1 is provided with a second rectangular groove 6. The detection chamber 503 is connected to the drying chamber 9 on both sides of the end facing the air inlet pipe 3. The end of the second rectangular groove 6 away from the drying chamber 9 is connected to the air outlet pipe 7. The end of the air outlet pipe 7 away from the second rectangular groove 6 is provided with an air outlet 8, and the air outlet 8 is located on the side of the detection chamber 1.

[0021] Please see Figure 3 and Figure 4The control component 502 is installed in the inner cavity of the second rectangular slide 6, the rectangular connecting block 504 is installed in the inner cavity of the first rectangular slide 508, and a miniature fan is installed in the inner cavity of the air inlet pipe 3.

[0022] Specifically, the hydrophobic modified silica gel used in the control component is modified with non-polar groups on its surface, which adsorbs only water molecules in the air and does not adsorb target gases such as formaldehyde and TVOC. This solves the problem of "non-specific adsorption" of detection gases by traditional moisture-absorbing materials. At the same time, this structure can stably control the humidity of the air entering the detection chamber 503 to below 50%RH, thereby improving the accuracy of the collected data. Moreover, the humidity control component 5, through the cooperation of the electric telescopic rod 501 and the drying chamber 9, realizes the automatic switching and drying regeneration of the moisture-absorbing silica gel 507, thereby reducing maintenance costs and avoiding monitoring interruptions caused by frequent downtime maintenance.

[0023] Please see Figure 5 A color-changing ambient light based on ambient air quality detection and its control system includes a humidity control module, a sensor module, a data processing module, a control module and an ambient light module; The humidity control module is used to control the humidity of the gas being detected; Based on the humidity control module, the sensor module is used to collect PM2.5 concentration, formaldehyde concentration and TVOC concentration in ambient air; Based on the sensor module, the data processing unit is used to filter, double-calibrate, and perform multi-parameter fusion analysis on the collected parameters to obtain the air quality level. In addition, the data processing unit will periodically calibrate the sensor drift problem through the double calibration mechanism. The control module, based on the data processing module, is used to generate lighting control commands according to the air quality level. Based on the control module, the ambient light module is used to make the ambient light 2 display the corresponding color, brightness and dynamic effects according to the light control command. The dynamic effects are matched according to the level (e.g., heavy pollution → fast red flashing, light pollution → slow yellow flashing). The color switching adopts a 3-second linear gradient to avoid abrupt changes. At the same time, the ambient light module has a built-in status feedback chip to monitor the working status of the light in real time and send the data back to the control module. If a light malfunction or abnormal color display occurs, the system will immediately push a warning message through the mobile APP to prompt the user to check and ensure the normal operation of the system and the reliability of the interactive functions. The temperature control module ensures that the humidity content of the gas being detected is less than 50%. At this time, the gas being detected enters the detection chamber 503 through the moisture-absorbing silica gel 507. As the gas continuously flows into the detection chamber 503, it exerts a thrust on the louvers 505, causing them to rotate and allowing the gas being detected in the detection chamber 503 to be transported to the outside. As the gas passes through the detection chamber 503, various sensors collect the concentrations of PM2.5, formaldehyde, and TVOC in the ambient air and transmit them to the data processing unit through the sensor module. The data processing unit then filters, performs dual calibration, and conducts multi-parameter fusion analysis on the collected parameters to obtain the air quality level. The control module then generates lighting control commands based on the air quality level and instructs the ambient light module to display the corresponding color, brightness, and dynamic effects of the ambient light 2 according to the lighting control commands.

[0024] Specifically, a closed-loop correction is formed through a dual calibration mechanism: automatic calibration is triggered every 30 days at midnight, and deviations are corrected by comparing with the "clean air baseline value"; and users can calibrate with one click through the APP. In this way, the authenticity of the detection values ​​can be improved by the dual dynamic calibration mechanism of the automatic calibration module and the user calibration module, thereby improving the accuracy of the data collected by the sensor. This allows users to make timely corrections when they find data anomalies.

[0025] Please see Figure 5 The data processing module includes a seasonal threshold adjustment module, a hazard level module, and a dual calibration mechanism module; The seasonal threshold adjustment module analyzes air quality characteristics in different seasons and presets a threshold correction table in the control unit. It then automatically identifies the season via a real-time clock, triggering threshold switching. The threshold correction table is as follows: Winter (November to February of the following year): PM2.5 "light pollution" threshold decreases from 75 μg / m³ 3 Relaxed to 90 μg / m 3 This reduces frequent color changes caused by short-term fluctuations; Summer (June-August): The threshold for "excellent" formaldehyde levels is 0.08 mg / m³. 3 Tightened to 0.07 mg / m 3 Early warning of the risk of formaldehyde volatilization under high temperatures; The hazard level module is used to determine the hazard level of pollutants based on surveyed medical data: formaldehyde carcinogenicity > PM2.5 respiratory damage > TVOC irritation. Priority judgment logic is written into the control unit. When multiple parameter results conflict, the lights are forced to be driven by the level of the higher priority parameter. The air quality rating uses "internationally recognized safety colors" and provides color explanation diagrams in the app, while also supporting user-defined colors.

[0026] Specifically, the hazard level module prioritizes health risks in the order of "formaldehyde > PM2.5 > TVOC," resolving the logical confusion caused by multiple conflicting parameters. Meanwhile, the seasonal threshold adjustment module dynamically switches thresholds based on winter and summer air quality characteristics. This prioritization of health risks and seasonal threshold adjustment avoids the impact of seasonal differences on air quality, while also preventing situations where fixed threshold settings lead to frequent lighting or delayed warnings.

[0027] Please see Figure 5 The dual calibration mechanism module includes an automatic calibration module and a user calibration module; The automatic calibration module is used to write a time-triggered function into the device firmware. Calibration is started every 30 days between 2 and 4 a.m. The current sensor reading is compared with the "clean air reference value" stored at the factory. If the deviation exceeds 15%, the compensation coefficient matrix is ​​automatically called for correction. The user calibration module is used to develop a "one-click calibration" entry in the mobile APP, guiding users to trigger it after opening windows for ventilation for 1 hour. Then the system sets the detection value at this time as the new benchmark and reverse-calculates the compensation coefficient to finally calibrate the sensor drift problem. Mathematical expression of the compensation coefficient matrix For the three types of sensors—formaldehyde, PM2.5, and TVOC—the compensation coefficient matrix can be expressed as: K = \begin{bmatrix} k_{F1} & k_{F2} & k_{F3} \\ k_{P1} & k_{P2} & k_{P3} \\ k_{T1} & k_{T2} & k_{T3} \end{bmatrix} in: The row vectors correspond to the formaldehyde (F), PM2.5 (P), and TVOC (T) sensors, respectively; The column vectors correspond to the temperature and humidity compensation coefficient (k1), aging compensation coefficient (k2), and baseline drift compensation coefficient (k3), respectively. The matrix element kᵢⱼ ranges from 0.8 to 1.2. When the detected value is too high, kᵢⱼ < 1, and when it is too low, kᵢⱼ > 1. Based on the influence of temperature and humidity on different sensors, the following conclusions were drawn through fitting experimental data: Formaldehyde sensor: k_{F1}=1+0.005×(60-RH)+0.003×(25-T) (RH is the actual relative humidity, and T is the actual temperature; when RH > 60% or T > 25℃, k_{F1} is increased to correct the problem of low detection value.) PM2.5 sensor: k_{P1}=1+0.002×(RH-50) (When RH > 50%, k_{P1} is reduced to correct for the high detection value caused by water mist interference.) TVOC sensor: k_{T1}=1+0.004×(30-T) (When T > 30℃, k_{T1} is increased to correct the low detection value caused by the increased volatilization of volatile organic compounds).

[0028] Please see Figure 5 The humidity detection module is used to detect the humidity of the hygroscopic silica gel 507. If the humidity exceeds 50%, the processing unit will activate the electric telescopic rod 501 to retract, so that the hygroscopic silica gel 507 connected to one end of the control frame 506 corresponds to the drying chamber 9, and the drying chamber 9 dries the hygroscopic silica gel 507 until the hygroscopic silica gel 507 connected to one end of the control frame 506 is dried, and then the drying chamber 9 stops. At this time, if the humidity of the hygroscopic silica gel 507 connected to the other end of the control frame 506 is detected to exceed 50%, the electric telescopic rod 501 will be activated to extend, so that the hygroscopic silica gel 507 connected to the other end of the control frame 506 corresponds to the drying chamber 9, and dries it.

[0029] Working principle: First, the miniature fan inside the air inlet duct 3 is activated. At this time, the air first passes through the front filter 4 and filters out large particles such as hair to avoid clogging subsequent components. Then, the air enters the inner cavity of the humidity control component 5 through the air inlet duct 3. The control frame 506 of the control component 502 is filled with hydrophobic modified silicone. Its porous structure and non-polar groups on the surface only adsorb water molecules in the air, while not affecting the passage of target gases such as formaldehyde and TVOC, so that the humidity of the air entering the detection chamber 503 is controlled below 50%RH. During the humidity control process of the humidity control component 5, when the humidity detection module detects that the humidity of the moisture-absorbing silica gel 507 exceeds 50%, the control unit of the electric telescopic rod 501 starts the electric telescopic rod 501 to retract, and drives the control frame 506 to move along the second rectangular slide groove 6, so that the moisture-absorbing silica gel at one end of the control frame 506 is aligned with the drying chamber 9, and the drying chamber 9 removes the moisture from the silica gel by heating; if the humidity of the silica gel at the other end also exceeds the standard, the electric telescopic rod 501 extends, switching to the other end of the silica gel for drying, ensuring continuous and efficient dehumidification. Humidity-controlled air enters the detection chamber 503, where PM2.5, formaldehyde, and TVOC sensors begin to detect the gas. The detected gas then drives the louver 505 to rotate, eventually expelling the gas to the outside and preventing it from lingering inside the chamber and affecting monitoring accuracy. Furthermore, the sensor module transmits the collected PM2.5, formaldehyde, and TVOC concentration data to the data processing module. Then, a moving average algorithm is used to eliminate instantaneous fluctuations. The automatic calibration module starts every 30 days between 2-4 AM, comparing the current reading with the factory "clean air baseline value". If the deviation exceeds 15%, the compensation coefficient matrix is ​​called to correct it. In addition, users can perform "one-click calibration" via a mobile APP (triggered after 1 hour of ventilation). The system uses the current detection value as the new baseline, reverse-calculates the compensation coefficient, and corrects the drift caused by sensor aging. Finally, the processed data is sorted according to the priority of the hazard level module "formaldehyde > PM2.5 > TVOC". If there is a parameter conflict, the higher priority parameter takes precedence. At the same time, the threshold is automatically switched according to the season based on the real-time clock to finally determine the air quality level. Once the air quality level is determined, the control module will generate corresponding lighting control commands based on the air quality level output by the data processing module, and send the commands to the ambient light module. When the ambient light module receives the commands, it will drive the ambient light 2 on the upper end of the detection chamber 1 to display the corresponding color, brightness and dynamic effects, so that the user can intuitively perceive the control quality, and then all operations will end.

As the gas being detected passes through the detection chamber (503), each sensor will collect the PM2.5 concentration, formaldehyde concentration and TVOC concentration in the ambient air and transmit them to the data processing unit through the sensor module. At this time, the data processing unit will filter, double-calibrate and multi-parameter fusion analysis of the collected parameters to obtain the air quality level. Then the control module will generate a lighting control command according to the air quality level and allow the ambient light module to make the ambient light (2) present the corresponding color, brightness and dynamic effect according to the lighting control command.

6. The control system for a color-changing ambient light based on ambient air quality detection according to claim 5, characterized in that: The data processing module includes a seasonal threshold adjustment module, a hazard level module, and a dual calibration mechanism module; The seasonal threshold adjustment module is used to analyze the air quality characteristics of different seasons and preset a threshold correction table in the control unit. Then, it automatically identifies the season through a real-time clock, triggers the threshold switching, and the threshold correction table is as follows: Winter (November to February of the following year): PM2.5 "light pollution" threshold from 75 μg / m³ 3 Relaxed to 90 μg / m 3 This reduces frequent color changes caused by short-term fluctuations; Summer (June-August): The "excellent" threshold for formaldehyde is 0.08 mg / m³. 3 Tightened to 0.07 mg / m 3 Early warning of the risk of formaldehyde volatilization under high temperatures; The hazard level module is used to determine the hazard level of pollutants based on surveyed medical data: formaldehyde (carcinogenic) > PM2.5 (respiratory damage) > TVOC (irritant), and priority judgment logic is written into the control unit. When multiple parameter results conflict, the lights are forced to be driven by the level of the higher priority parameter. The air quality levels use "internationally recognized safety colors" and provide color explanation diagrams in the app, while also supporting user-defined colors.

7. The color-changing ambient light and its control system based on ambient air quality detection according to claim 6, characterized in that: The dual calibration mechanism module includes an automatic calibration module and a user calibration module; The automatic calibration module is used to write a time-triggered function into the device firmware, which starts calibration every 30 days from 2 to 4 a.m. It compares the current sensor reading with the "clean air reference value" stored at the factory. If the deviation exceeds 15%, it automatically calls the compensation coefficient matrix for correction. The user calibration module is used to develop a "one-click calibration" entry in the mobile APP, guiding users to trigger it after opening windows for ventilation for 1 hour. Then the system sets the detection value at this time as the new benchmark and reverse-calculates the compensation coefficient to finally calibrate the sensor drift problem.

8. The color-changing ambient light based on ambient air quality detection and its control system according to claim 7, characterized in that: The humidity detection module is used to detect the humidity of the hygroscopic silica gel (507). If the humidity exceeds 50%, the processing unit will activate the electric telescopic rod (501) to retract, so that the hygroscopic silica gel (507) connected to one end of the control frame (506) corresponds to the drying chamber (9), and the drying chamber (9) dries the hygroscopic silica gel (507) until the hygroscopic silica gel (507) connected to one end of the control frame (506) is dried, and the drying chamber (9) is stopped. At this time, if the humidity of the hygroscopic silica gel (507) connected to the other end of the control frame (506) is detected to exceed 50%, the electric telescopic rod (501) will be activated to extend, so that the hygroscopic silica gel (507) connected to the other end of the control frame (506) corresponds to the drying chamber (9), and the drying operation will be performed.
