LED Particle Sensor PM1003

LED Particle Sensor PM1003


PM1003 is an infrared (LED) particle sensor, designed to detect the variation trend of particle concentration size between 1.0μm~10μm adopting the principle of optical scattering principle. It can show the dust concentration in the air by detecting the intensity of reflected light. Sensor can output measuring value by PWM or UART signal.
