iHaospace PMS7003 Sensor Module PM2.5 Air Particle Dust Sensor PM2.5 Concentration Laser Detection Sensor Module

The sensor uses the principle of laser scattering. It means that the laser light on the particles in the air and making the scattering, while collecting scattered light at a particular angle , resulting in scattered light intensity with time curve. The principle of laser scattering to achieve accurate measurement Zero error alarm rate Real-time response and support for continuous acquisition Minimal resolution particle size 0.3um
