YJJ PMS3003 Laser PM2.5 PM10 Dust Sensor UART Digital Particle Detection Module

Product Description:

YJJ PMS3003 Laser PM2.5 PM10 Dust Sensor UART Digital Particle Detection Module

Features:

I. Product Introduction

PMS3003 is the third-generation laser scattering type dust sensor, equipped with a miniature air intake fan; it outputs PM1.0, PM2.5, PM10 mass concentrations and the number of particles of multiple sizes via TTL-UART serial port. Compared with PMS1003, it has improved anti-interference and stability, with a metal shielding shell, suitable for indoor and outdoor air quality equipment development.
