J-Sensor

Laser particle sensor

Product introduction

The particle sensor is a laser digital particle detection sensor, which can be used in indoor and outdoor air tiny particles detection. It contains a laser and a photoelectric receiving device, which works in the principle of light scattering. By scattering light on the dust particles with a laser and converting it from a photoelectric converter to an electrical signal, then the mass concentration of particulate matter can be calculated by the software algorithm.
