PM2.5 PM10 TSP RS485

This PM2.5 / PM10 / TSP (Total Suspended Particles) sensor is a high-precision device designed for environmental and industrial dust monitoring. It uses laser scattering technology to detect fine and coarse particulate matter, including total airborne dust. The RS485 Modbus RTU output ensures reliable, long-distance communication, making it ideal for smart city air monitoring, industrial dust control, and environmental research.

Built for outdoor and harsh environments, the sensor can be integrated into air monitoring stations, IoT systems, and dust control equipment.
