Laser Dust Sensor FS00218 Introduction

FS00218 is a weight-type dust sensor composed of an optical sensing system, which consists of an infrared light-emitting tube, an infrared receiving tube, a lens, a light-shielding casing, a shielding cover and a circuit board. When the airflow-carrying dust particles passes through the detection area irradiated by the infrared light-emitting tube, the forward scattered light generated is received by the photoelectric receiving tube, and a voltage signal proportional to the dust concentration is output after the signal is amplified.

Laser Dust Sensor FS00218 Features

1.Very Large Scale Integration (VLSI) Circuit

VLSI technology can improve the working speed and power efficiency of chips, thereby providing better performance.


2.Adopting a low-power ARM solution

Low-power ARM technology can significantly reduce system energy consumption, thereby extending battery life.


3.The minimum resolution particle size is 0.3 micrometers

The high sensitivity and quick response can detect minimum size of particle is down to 0.3 micrometers.


4.Fully shielded design, anti-static interference

High stability, high accuracy, longer service life, reliable adaptability, wide application areas.


5.Long service life, accurate and stable data

Lifetime: The service life is up to 40000 hours (Continues work)
