Laser Dust Sensor FS00203 Introduction

FS00203 laser dust sensor is a digital general particle concentration sensor used to obtain the mass concentration (μg/m³) of suspended particles in the air, such as PM1.0, PM2.5, and PM10, and the number of particles with sizes 0.3, 0.5, 1.0, 2.5, 5.0, and 10um per unit volume. It outputs data in digital interface form. 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.

Laser Dust Sensor FS00203 Features
