Principle Introduction

The Carbon Dioxide(CO2) gas sensor is for air quality. It is chemical type gas sensor that adopts solid electrolyte cell principle, used to detect carbon dioxide. When sensors are exposed to CO2, battery is positive and negative electrode reaction, the CO2 sensor produces electromotive force between sensitive electrode and reference electrode, the output voltage signal can be detected carbon dioxide.

Features

High sensitivity to CO2 

Low cost,   long life 

Good stability 

Simple application circuit

Low power consumption

Application

Air purifier,  HAVC refrigeration,  Indoor air quality monitoring,  Intelligent integrated ceiling,  Range hood, air conditioner
