2.9 Air purifier
Leiditech recommends air purifier protection devices and solutions
The air purifier mainly consists of a motor, fan, air filter screen, and other auxiliary purification devices, such as a negative ion generator, high-voltage circuit, etc. The quality of the air filter directly affects the effectiveness of the air purifier. This plan is mainly designed for the electronic control system of the air purifier. In the system design, the concentration of PM2.5 in the air is detected through dust sensors. At the same time, the temperature and humidity data in the air and the air quality detection data, which are the three main input data, are transmitted to the MCU. After being processed by a single chip computer, the parameters are presented in the display module, which has an over limit alarm function. At the same time, communication can be carried out through the Wi module, Transfer the collected data to the mobile app.
In recent years, the air purifier industry has developed rapidly. Although the air purifier industry is currently developing rapidly, the penetration rate of air purifiers in American households is 27%, Japan is 17%, and China is around 1%. It can be seen that there is still considerable room for development in the Chinese air purifier market. And the MCU microcontroller plays a crucial role.
