PM2.5 laser sensors, also known as laser dust sensors, use the laser scattering principle to detect the concentration of dust particulate matter in the air.

The light source of the PM2.5 laser sensor is a laser diode. Sampling air is obtained through airflow generated by a fan, which passes through a specially designed air duct. When fine particles in the air enter the laser beam area, they cause the laser to scatter. Scattered light radiates 360° in space, and a photodetector inside the laser sensor receives this light. The photoelectric effect then generates a current signal, which is amplified and processed to obtain the fine particle concentration value.

Application areas for PM2.5 dust laser sensors: air purifiers, air conditioners with purification functions, PM2.5 detectors, range hoods, smoke alarms, fresh air systems, dedicated PM2.5 sensors, air probes, wearable devices, etc.

Luftmy's laser PM2.5 sensors can detect suspended particle concentrations from 0.1 to 10 microns in the air. Using imported lasers and photosensitive components, the data is stable and reliable; with a built-in fan and digital output, the integration is high. By adopting optimized optical paths, air duct designs, and self-calibration parameter algorithms, the PM2.5 consistency is excellent. The size, installation method, and signal interface are compatible with most infrared dust sensors, making it an ideal upgrade product.
