Infrared LED Particle Sensor PM1003

Air Purifier; Air Filter

Introduction

Infrared LED particle sensor module PM1003 adopts the principle of optical scattering to detect the variation trend of particle (size between 1μm to 10μm) concentration in the air. There is an infrared light-emitting diode and an optoelectronic sensor built-in PM1003, 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 detect the intensity of reflected light. Sensor can output measuring value by PWM or UART signal.

Advantages

The sensor has the leading detection stability among the infrared LED particle sensor in the market and can decrease the interference of outside environment through the electromagnetic screen design.

The filter circuit and MCU software program of the sensor is designed to filter out noise signals so that the data output is more stable and reliable.
