Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to an environmental monitoring device. Background Technology

[0002] Infants and toddlers are a special group whose comfort needs in indoor environments differ from adults, especially regarding temperature and humidity. On the one hand, they are highly sensitive to environmental comfort; on the other hand, they cannot effectively express their feelings of thermal comfort. Furthermore, they lack the ability to independently regulate their indoor environment, and their clothing and environmental adjustments typically rely on the decisions of their caregivers. Because caregivers (adults) and infants / toddlers perceive changes in temperature differently, caregivers often overlook these changes or make decisions unsuitable for the comfort needs of infants / toddlers. Therefore, it is necessary to monitor indoor environmental parameters in the spaces where infants and toddlers reside. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an environmental monitoring device for monitoring indoor environmental parameters of the space where infants and young children are located.

[0004] To achieve the above and other related objectives, this utility model provides an environmental monitoring device, comprising: a master device and a slave device, wherein the master device and the slave device are wirelessly connected via a wireless communication network; wherein both the master device and the slave device are equipped with sensors for detecting environmental parameters and batteries for power supply, and the master device is also equipped with a controller and an alarm module.

[0005] The controller is configured to receive sensor data wirelessly transmitted from the slave device, compare the sensor data of the slave device with the sensor data of the master device, and generate an alarm command based on the comparison result.

[0006] The alarm module is connected to the controller and is used to receive the alarm command and perform audible and visual alarms according to the alarm command.

[0007] In one embodiment of the present invention, the alarm module includes a voice module and a light module, wherein the voice module is used to provide sound alarms and the light module is used to provide light alarms.

[0008] In one embodiment of this utility model, both the master device and the slave device are equipped with a temperature sensor, a humidity sensor, a carbon dioxide sensor, a TVOC sensor, a WIFI controller, and a data storage device.

[0009] In one embodiment of this utility model, the controller is composed of an ESP32 chip.

[0010] In one embodiment of the present invention, the temperature sensor is composed of a DHT11 chip, and / or the humidity sensor is composed of a DHT11 chip.

[0011] In one embodiment of the present invention, the carbon dioxide sensor is composed of a CCS881 chip, and / or the TVOC sensor is composed of a CCS881 chip.

[0013] In one embodiment of this utility model, the lighting module includes a yellow light alarm or a red light alarm.

[0014] In one embodiment of this utility model, the voice module includes multiple sound contents.

[0015] As described above, this utility model provides an environmental monitoring device with the following beneficial effects: Two devices, each equipped with sensors for detecting environmental parameters and a battery for power supply, can be used as a master device and a slave device, respectively. A controller and an alarm module are then installed within the master device. The controller compares the sensor data from the master and slave devices, and the alarm module provides audible and visual alarms based on the comparison results, thus enabling environmental monitoring. If the master device is placed indoors where the infant's guardian is located, and the slave device is carried with the infant, when the infant returns indoors from outdoor activities, the slave device automatically connects to the master device via a wireless communication network and transmits the environmental parameters recorded on the slave device to the master device.

[0020] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides an environmental monitoring device, including a master device and a slave device. Both the master and slave devices have a Wi-Fi controller. The master device's Wi-Fi controller operates in AP mode, while the slave device's Wi-Fi controller operates in STA mode. Wi-Fi pairing information is pre-configured at the factory or negotiated during activation. Afterward, the master and slave devices can wirelessly connect within the near-field range via a wireless communication network. Both the master and slave devices internally include sensors for detecting environmental parameters and batteries for power supply. The master device also includes a controller and an alarm module. In this embodiment or other embodiments, the master and slave devices can internally incorporate communication chips, communication modules, and communication circuits supporting wireless communication networks as Wi-Fi controllers, enabling the master and slave devices to connect wirelessly in the near field via Wi-Fi.

[0021] The controller receives sensor data wirelessly transmitted from the slave device, compares the sensor data from the slave device with the sensor data from the master device, and generates alarm commands based on the comparison results. As an example, in this embodiment or other embodiments, the controller is composed of an ESP32 chip.

[0022] The alarm module is electrically connected to the controller and is used to receive alarm commands and provide audible and visual alarms based on the alarm commands. As an example, in this embodiment or other embodiments, the alarm module includes a voice module and a light module, wherein the voice module is used to provide audible alarms and the light module is used to provide visual alarms.

[0023] In one exemplary embodiment, both the master device and the slave device are internally equipped with a temperature sensor, a humidity sensor, a carbon dioxide sensor, a TVOC sensor, a Wi-Fi controller, and a data storage device. Specifically, as shown... Figure 2As shown, the temperature and humidity sensors are both composed of DHT11 chips, while the carbon dioxide and TVOC sensors are both composed of CCS881 chips. The DHT11 chips constituting the temperature and humidity sensors, and the CCS881 chips constituting the carbon dioxide and TVOC sensors, are all electrically connected to the ESP32 chip constituting the controller. The data storage device is used to store the sensor data detected by the temperature, humidity, carbon dioxide, and TVOC sensors.

[0024] In one exemplary embodiment, the main device further includes a display screen for displaying sensor data. The display screen in the main device includes, but is not limited to, an OLED (Organic Light-Emitting Diode) display screen. Figure 3 As shown, the display screen can be electrically connected to the ESP32 chip that constitutes the controller.

[0025] In one exemplary embodiment, the lighting module includes a yellow light alarm or a red light alarm. For example... Figure 3 As shown, the lighting module can be electrically connected to the ESP32 chip that constitutes the controller. The lighting module can include red, yellow and green lights, where red light indicates a red light alarm, yellow light indicates a yellow light alarm, and green light indicates no alarm.

[0026] In one exemplary embodiment, the voice module includes multiple sound contents. As an example, in this embodiment or other embodiments, the voice module may be constructed using a SYN6288 chip. Figure 3 As shown, the SYN6288 chip that constitutes the voice module can be electrically connected to the ESP32 chip that constitutes the controller.

[0027] According to the above description, in a specific embodiment, the voice module, alarm module, and display module can be reset and initialized first. When the master device and slave device are connected to the same Wi-Fi network, the slave device wirelessly transmits sensor data from the slave device to the master device via Wi-Fi. The controller in the master device receives the sensor data from the slave device. Simultaneously, the controller in the master device compares the sensor data of the master device with that of the slave device. If the difference between the sensor data of the slave device and the sensor data of the master device is large, or if the sensor data of the slave device is greater than that of the sensor data of the master device, the controller in the master device generates an alarm command based on the comparison result. As an example, when the difference between the temperature sensor data of the slave device and the temperature sensor data of the master device is greater than 5°C, the controller in the master device can generate a first alarm command. At this time, the alarm module drives the yellow LED to light up according to the first alarm command. When the difference between the temperature sensor data of the slave device and the temperature sensor data of the master device is greater than 10°C, the controller in the master device can generate a second alarm command. At this time, the alarm module drives the red LED to light up according to the second alarm command and drives the voice module to play a voice alarm prompt saying "The indoor and outdoor temperature difference is large, please pay attention". As another example, when the humidity sensor data from the slave device exceeds 70%, the controller in the master device can generate a third alarm command. At this time, the alarm module will activate a red LED and the voice module will play a voice alarm message stating, "The environment around the child is humid; please be careful." When the humidity sensor data from the slave device is less than 50%, the controller in the master device can generate a fourth alarm command. At this time, the alarm module will activate a red LED and the voice module will play a voice alarm message stating, "The environment around the child is dry; please be careful." As yet another example, when the carbon dioxide sensor data from the slave device exceeds 700, the controller in the master device can generate a fifth alarm command. At this time, the alarm module will activate a red LED and the voice module will play a voice alarm message stating, "The carbon dioxide concentration around the child is too high; please be careful." As another example, when the TVOC sensor data of the slave device is >100, the controller in the master device can generate a sixth alarm command. At this time, the alarm module drives the red LED to light up according to the sixth alarm command and drives the voice module to play the voice alarm message "The TVOC concentration in the surrounding environment of children is too high, please pay attention".

[0028] Therefore, this utility model provides an environmental monitoring device that uses two devices, each equipped with sensors for detecting environmental parameters and a battery for power supply, as a master and slave device, respectively. These devices are wirelessly connected via a wireless communication network such as Wi-Fi. A controller and alarm module are installed within the master device. The controller compares the sensor data from both devices, and the alarm module provides audible and visual alarms based on the comparison results, thus enabling environmental monitoring. If the master device is placed in the indoor space where the infant's guardian is located, and the slave device is carried with the infant, this utility model can continuously record the infant's real-time environmental parameters. When environmental parameters deviate from requirements, it proactively alerts the guardian through audible and visual alarms, allowing the guardian to promptly check or adjust the infant's real-time environmental parameters and reduce the impact of adverse environmental factors on the child's health. This invention uses one device as the main device for indoor environmental monitoring and another device carried by the infant as a slave device for real-time environmental monitoring. The main and slave devices are wirelessly connected via a wireless communication network and can continuously record real-time environmental parameters of the infant, including but not limited to temperature, humidity, noise, and carbon dioxide concentration. For example, when the two devices are less than 50 meters apart or when the infant returns indoors from outdoor activities, the slave device automatically connects to the main device via Wi-Fi and synchronizes the information recorded by the slave device, transmitting the environmental parameters recorded by the slave device to the main device. When the main device receives the environmental parameters transmitted by the slave device, it compares them with the environmental parameters recorded by the main device. The main device calculates the difference between indoor and outdoor environmental parameters. If the difference exceeds a threshold, the main device proactively reminds the caregiver to adjust the indoor environmental parameters. Therefore, this invention, based on the comfort needs of children, intelligently analyzes and sends reminders to caregivers, thereby reducing the impact of adverse environmental factors on children's health.
