This product uses Mie scattering principle to detect dust particles in the air, with good consistency and stability. The collected PM value is transmitted to the monitoring terminal through RF communication in real time to achieve uninterrupted and accurate measurement. This product uses the 470MHz LoRa wireless communication technology platform. The communication protocol uses the Internet of Things micro power wireless network communication protocol of the State Grid power transmission and transformation equipment to achieve dual-way communication. It also has RS485 communication mode to meet the user's multiple communication needs, achieve intelligent management of the air quality of the operating environment of power equipment, and provide data support for the safe operation of power grid equipment.
