$ Cubic Infrared LED Particle Sensor PM1006K Introduction Infrared LED particle sensor module PM1006K adopts the principle of optical scattering to detect the variation trend of particle (size between 1pm to 10 pm) concentration in the air. There is an infrared light-emitting diode and an optoelectronic sensor built-in PM1006K, and light rays from the light-emitting diode will be reflected when pass through the particle. The optoelectronic sensor can show the concentration of particle in the air by detecting the intensity of reflected light. Sensor can output measuring value by pulse or UART...

Internal architecture and principle description Light scattering principle According to the above picture, the light source of PM1006K is consist of LED which launch to detecting particles light, front-loading lens and drive circuit. The detecting part is consist of postposition condensing lens, photoelectric part which receives reflected light and amplifying circuit. The particle measuring principle of PM1006K The LED light generates reflected light when meet particles. Photoelectric diode detects the light intensity of reflected light, judging the particle concentration according to pulse signal....

User attention ※ Ensure the ventilation of air inlet and air outlet in installation; ※ The sensor should not be used in the environment with organic gas and flammable gas. If there is dust in the chamber of the sensor, please clean with cleaner; ※ The product should be kept away from high frequency and high voltage source to avoid the interference caused by high frequency and high pressure. The measurement error of the sensor would be increased by the external light affection. Therefore, the external light should be avoided when installation; ※ The measurement error of the sensor would be increased...
