Online Monitoring System for Noise and Dust

●Support 1x shutter box (temperature, humidity, noise, air pressure) acquisition.
●Support 1x wind speed acquisition, 1x wind direction acquisition, and 1x relay output (default can be connected to on-site secondary relay control fog cannon).
●Upload data to the monitoring software platform through 4G mode, and be able to connect to an external LED screen (54cm * 102cm) to display the current numerical information in real-time.
