The noise and dust monitoring system can carry out continuous automatic monitoring of monitoring points in the dust monitoring area of different sound and environmental functional areas. It is a monitoring device with complete functions. It can automatically monitor data in the case of unattended, and can automatically monitor data through GPRS/CDMA mobile public network and dedicated line. network, etc. to transmit data. It is an all-weather outdoor dust monitoring system developed by itself to improve air quality using wireless sensor technology and laser dust testing equipment. In addition to dust monitoring, it can also monitor PM2.5, PM10, PM1.0, TSP, noise, and ambient temperature. Environmental factors such as environmental humidity, wind speed and wind direction, and the test data of each test point are directly uploaded to the monitoring background through wireless communication, which greatly saves the monitoring cost of the environmental protection department and improves the monitoring efficiency. Mainly used for urban functional area monitoring, industrial enterprise boundary monitoring, construction site boundary monitoring.
