Product Description:

YJJ PMS1003 Laser PM2.5 PM10 Dust Sensor UART Digital Air Particle Detection Module

Features:

I. Product Introduction

PMS1003 is a general-purpose laser scattering type particulate matter sensor, equipped with a miniature fan for suction and sampling, TTL-UART digital output. It can simultaneously detect multiple particle size ranges of 0.3 - 10 μm dust and output PM1.0/PM2.5/PM10 concentrations. It is mainly used in air detection instruments, purifiers, and environmental monitoring equipment development.
