摘　　要：With the rapid development of the society, the familial pollution of the gas, industrial waste gas and so on made the air pollution is more and more serious. The improvement of living standard, people become more and more concerned about the quality of the air. However, the related testing and purify device are very few. Under this condition, small range of mobile air purification equipment's application has good prospects. This paper introduced the testing of air quality, the composition of test parameters equipment, its working principle and hardware circuit and software design process. In the system, for the core to STC12C5A60S2, which through DHT21 to test the environment temperature, humidity test and use DSM501A detect the content of particle. What's more, use QS-01 to measure the air pollutants content and show on NOKIA5110 liquid crystal in real time. After the test results show that the system runs stability, have certain effect to air purification and fit for indoor or out of air purification.
