PM1003A LED Particle Sensor

PM1003A is an infrared LED particle sensor module, designed to detect the variation trend of particleconcentrationsize between 1.0μm~10μm with adopting the principle of optical scattering principle. There is aninfraredlight-emitting diode and an optoelectronic sensor built-in PM1003A, and light rays from the light-emittingdiodewillbe reflected when passing through the particle. It can show the dust concentration in the air by detectingtheintensity of reflected light. Sensor can output measuring value by PWM or UART signal.
