Abstract：To monitorand study the changes of ambient airqualityin Zhuhai City，anambientair quality monitoring system was designed based on high-sensitivity sensor technology.The systemuses STM32F103VET6 as the main control chip and RS485 communication as the communication protocol. By using temperature and humidity dual sensorsand sulfur dioxide sensors to analyzethe ambient air in Zhuhai，theambient air quality change monitoring in Zhuhai is realized.The testresults show that the system can sensitively perceive the change of ambient air temperatureand humidity，which is close tothe ambient air temperatureand humiditycollectedby the national controlsite，andcan transmitthecollctedtemperatureand humiditydatatotheclientinreal time，whichimproves the real-time andaccuracyof ambient air quality monitoring，and hascertainreliability，effectiveness and practical application value.
