Product Description:

YJJ PMS9103M Laser PM2.5 PM10 Dust Sensor UART Digital Air Particulate Detection Module

Features:

I. Product Introduction

The PMS9103M is a new ultra-thin laser scattering particulate matter sensor with a thickness of only 12mm. It has a full-metal six-sided shielding shell. It is equipped with a micro suction fan and has TTL-UART digital output. It can detect particles with diameters ranging from 0.3 to 10μm, and outputs the mass concentrations of PM1.0/PM2.5/PM10. It features a lightweight and compact design, strong resistance to electromagnetic interference, and is suitable for portable devices and small air quality detectors.
