Embodiment 1

[0031] Embodiment 1 Overall system structure of the present invention

[0032] refer to figure 1 , the structure of the ARM-based smart home indoor environment detection device of the present invention includes a main control module 1, a formaldehyde gas monitoring module 2, and a communication module 3, wherein the main control module 1 is responsible for coordinating the work between the modules, and the formaldehyde gas monitoring module 2 Detect the concentration of formaldehyde gas in the current indoor air, and send the corresponding data to the main control module 1. At the same time, when the formaldehyde gas in the indoor air exceeds the standard, an alarm message is sent to the user's mobile phone through the communication module 3. The user's mobile phone number can be pre-existed for communication. In the module 3, on this basis, the temperature and humidity monitoring module 4 can also be added for real-time monitoring of the temperature and humidity in the room, ...

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an ARM-based smart household indoor environment monitoring device. Background technique [0002] As China's economic development is getting better and better, people's living standards are also improving rapidly. As a result, people's awareness of their living environment and their own healthy life is also increasing year by year. In particular, a video by Chai Jing, the host of CCTV (investigation on Fog Ting): Under the Curved Roof, has aroused the attention and resonance of many people. Therefore, the demand for indoor air quality monitoring has also become very large. Among them, the pollution problems that people in the country care about most in their lives are mainly in the following aspects. Harmful gases such as formaldehyde, benzene, volatile organic compounds and other carcinogens caused by house decoration, mold, smoking, insecticide sprays, and PM...
