The noise and dust monitoring station is a monitoring equipment specifically designed for construction projects in progress. This device has 1 channel of louver box (temperature, humidity, noise, PM2.5, PM10, air pressure, TSP) collection, 1 channel of wind speed collection, 1 channel of wind direction collection, and 1 relay output (default can be connected to on-site secondary relay control fog cannon); This device can upload data to the monitoring software platform via 4G, and the host can also be connected to an external LED screen (54cm * 102cm) to display real-time numerical information.
