PMS7003 Dust Sensor

The PMS7003 is a high-precision laser-based dust sensor designed to detect particulate matter (PM1.0, PM2.5, and PM10) in real time. Utilizing laser scattering technology and a built-in fan, it ensures stable, accurate, and continuous monitoring of air quality. This compact module is widely used in air purifiers, HVAC systems, smart home devices, and environmental monitoring equipment.

With its digital UART interface and ultra-low noise operation, the PMS7003 is ideal for both portable and stationary applications requiring real-time particle concentration analysis.
