PM2.5 / PM10 Laser Particle Sensor | Air Quality Dust Detection Module
A compact laser-based PM2.5 / PM10 particle sensor delivering real-time air quality data with high stability and easy integration. Ideal for air purifiers, environmental monitoring, HVAC systems, and IoT air quality devices.
This laser dust particle sensor module measures airborne particulate matter concentrations for PM2.5 and PM10 using optical scattering technology. An internal laser emitter and precision photodetector are arranged in a crossed optical path, enabling accurate detection of particles in the 0.3–10 μm size range.
Measured particle counts are converted internally using calibrated algorithms and output directly as mass concentration (µg/m³), simplifying system design and data processing. The sensor features automatic start-up self-calibration, ensuring consistent readings and long-term stability.
With a compact footprint, low power consumption, and digital-friendly outputs, the module is well suited for embedding into air purifiers, air quality monitors, smart buildings, HVAC systems, environmental stations, and IoT platforms.
