Design and Research of Intelligent Air Purifier System

In recent years, the environmental pressure has become increasingly serious, causing great concern of air purification that is regarded as a hot topic among people. The design of the intelligent air purifier introduced in this paper is mainly based on the principle of STM32F407MCU. The air purifier drives PM2.5 collection module to collect the information regarding air quality. After the air condition is tested, it is divided into three grades: superior, good and bad, the information of which will be transmitted to the display screen of the air purifier. People can choose the automatic mode or manual mode to adjust the purification level of the air purifier, and the test results will be transmitted to the mobile terminal of the mobile phone via the Bluetooth communication module. The air purifier introduced in this paper will make people’s life more artificial and intelligent. The experimental results show that the effective purification rate of the air purifier is 97%, and the sterilization rate is 99%.
