[0030] This invention proposes an air quality detection device with an e-ink screen and WiFi functionality.

[0031] In the embodiments of this utility model, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the air quality detection device with e-ink screen and WiFi function according to the present invention. The air quality detection device with e-ink screen and WiFi function includes:

[0032] Main control module 10, power button 20, reset and power off button 30, e-ink screen 40, buzzer 50, Grove interface 60, RTC timer 70, SEN55 sensor 80, power supply module 90;

[0033] The main control module 10 includes a WiFi unit 101 for connecting to WiFi signals. The main control module 10 is connected to the power button 20, the reset and power off button 30, the e-ink screen 40, the buzzer 50, the Grove interface 60, the RTC timer 70, the SEN55 sensor 80, and the power supply module 90. The e-ink screen 40 is used to display the air quality detection data collected by the SEN55 sensor 80.

[0034] Please see Figure 2 , Figure 2This is a schematic diagram of a specific embodiment of the air quality detection device with e-ink screen and WiFi functionality according to this utility model. The device offers flexible power supply options, supporting USB interface power supply with a voltage range of 5V, and also includes a built-in 4.2V 450mAh lithium battery as a backup power source. In case of power failure during outdoor air quality monitoring, emergency power can be provided via a power bank. When the device is powered on, the buzzer will emit two beeps, the power indicator light (red light) will remain constantly lit, and the screen will begin a power-on countdown. After entering the data collection interface, the device will start a default countdown for one minute, but users can also customize the countdown timer by connecting to the device's WiFi and setting it on a webpage. The device's network communication function relies on a WiFi connection to ensure that the collected data can be uploaded to the cloud. After device initialization and the air quality collection countdown ends, the screen will display various collected values, including key parameters such as CO2 concentration, temperature (Temp), relative humidity (RH), PM1.0, PM2.5, PM4.0, PM10 particulate matter concentration, volatile organic compound (VOC) concentration, and nitrogen oxide (NOx) concentration. Additionally, the screen will display Wi-Fi connection status, current date and time, and battery level. Without USB power, the power button can be used to power on the device; the power off button shares the same as the RST reset switch, and a long press will power off the device, at which point the power indicator light (red light) will turn off. The device also features a G0-BOOT programming port; pressing button A while connecting via USB allows for firmware programming. Furthermore, pressing button B once after successful power-on will prompt the user to connect to the device's Wi-Fi. The SEN55 sensor can accurately measure inhalable particulate matter within its range, including PM1.0, PM2.5, PM4.0, and PM10, and also has the ability to collect volatile organic compounds (VOCs) and oxidizing gases (NOx). For data acquisition and transmission, the sensor first digitizes the raw data using an internal analog-to-digital converter (ADC), and then efficiently transmits it to a microcontroller (MCU) via the I2C communication protocol. The MCU parses and processes the data through preset program logic, and finally transmits the processed data to an external display device so that users can intuitively view various environmental parameters. The device is also equipped with an RTC timed wake-up function for convenient timed data acquisition. This invention collects environmental data through the sensor (SEN55) and sends the data to the microcontroller (MCU) via the I2C communication interface. The microcontroller (MCU) processes and converts the data, calculating the actual physical quantities such as temperature, humidity, and air quality values. The LCD screen displays this data under the control of the microcontroller (MCU), providing real-time feedback to the user.The entire process begins with the device collecting sensor data, which is then uploaded to a cloud database via a WiFi network. Finally, the data is viewed, analyzed, and managed through smart devices. This approach enables real-time data interaction and remote monitoring between the device and the user, while also allowing for advanced functions such as data storage, analysis, and alarm notifications via the cloud platform. This not only improves data accessibility and real-time performance but also enhances intelligent management.
