Air quality detection system

The utility model relates to an air quality detection system. The air quality detection system comprises a monitoring center and at least one detection terminal, wherein the detection terminals are connected with the monitoring center in a communication mode; the monitoring center comprises a second microprocessor and a second communication module connected with the second microprocessor; the detection terminal comprises a first microprocessor, and a first communication module, an air quality detection module, a global position system (GPS) module and a display module connected with the first microprocessor; the air quality detection module detects surrounding air quality to acquire parameters of the air quality and sends the parameters of the air quality to the first microprocessor; and the first microprocessor sends the parameters of the air quality to the monitoring center by the first communication module, transmits the parameters of the air quality to the display module for displaying and sends positioning data acquired by the GPS module to the monitoring center. The air quality detection system is high in automation degree and high in intelligence, can greatly save the labor force and improves the detection efficiency of the air quality.
