Product Introduction

PMST003 is a digital universal particle sensor based on the laser scattering principle. It can continuously collect and calculate the number of suspended particles of different particle sizes in a unit volume of air, that is, the particle concentration distribution, and then convert it into mass concentration, and output it in a common digital interface format. This sensor can be embedded in various instruments or environmental improvement equipment related to the concentration of suspended particles in the air, providing timely and accurate concentration data.

Features

Laser scattering principle for precise measurement
Zero false alarm rate
Real-time response and supports continuous collection
Minimum resolution particle size 0.3µm
Six-sided full shielding structure, stronger anti-interference performance
Ultra-thin design of only 6 mm, suitable for portable devices

Applications

Air purifiers
Ventilation systems
Air quality monitors
HVAC systems
Portable environmental detection devices
