Design of multifunctional universal air quality detector based on skill competition

The design of this paper is based on the electronic product design and production event of the sixth local university skills competition in Zhengzhou.The design uses STC89C52 single chip microcomputer as the core,and also includes nine modules:power supply module,temperature and humidity detection module,PM2.5 detection module,LCD display module,key module,audible and visual alarm module,Bluetooth module and purification device module.The design can realize the real-time display of temperature,humidity and PM2.5 values on the LCD screen,and when any parameter reaches the limit value,it will send out audible and visual alarm signals respectively,start the purification device at the same time,and remotely monitor the system through the mobile phone.In addition,the power module also has a convenient design that the indoor regulated power supply can supply power to the system,and the outdoor charging treasure can supply power to the system.This design is a small size,low power consumption,multifunctional,portable,general air quality detector.
