With the intensification of air pollution, more and more home users are paying attention to indoor air quality, as people spend most of their time indoors. The PM2.5 portable detector is a specialized instrument used specifically for detecting the concentration of inhalable particulate matter in the air. Many families are equipped with such instruments because they are simple and convenient, allowing them to measure indoor air quality at any time and evaluate the purification efficiency of air purifiers.

The PM2.5 portable detector relies on a built-in PM2.5 sensor to detect concentration. When an infrared light source irradiates particulate matter passing through the detection position, light scattering occurs. The scattering intensity in the direction perpendicular to the light path is related to the particle diameter. By counting, the real-time particle number concentration can be obtained, and the mass concentration, unified with official units, can be derived according to empirical conversion formulas and calibration methods.

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