摘要	In view of the challenge that the National Ambient Air Quality Monitoring Station (NAAQMS) is not suitable for large area distribution due to its large volume and high cost, a miniature air quality monitoring system is developed to monitor the concentrations of CO, NO_2, O_3, SO_2, PM_(2:5) and PM_(10) in atmosphere. Electrochemical gas sensors and optical particle counter are adopted to measure the concentration of air pollutants and particles respectively in the system. Considering that the sensor is vulnerable to the influcence of temperature and humidity of atmosphere when measuring the concentration of pollutants, the measurement results are modified through the temperature and humidity compensation algorithm based on the multi-sensor fusion technology. Then the modified measurement results are compared with the data released by NAAQMS, and it is shown that there is a strong correlation between the two data. Compared with the data obtained from NAAQMS, the correlation coefficient for 10 days monitoring data obtained from the developled system is better than 0.7. After the algorithm correction, the correlation coefficient of some pollutants, such as PM2:5, can even be improved to 0.9. The air quality monitoring system is robust and small in size, which is suitable for long-term and large area distributed network monitoring of environmental air pollutants.
