Introduction

Dual beam (single light source, dual wavelength) CM1108 CO2 gas sensor module is mainly used to detect CO2 concentration by adopting non-dispersive infrared (NDIR) technology. It is widely used for ventilation system, agricultural greenhouse facilities, agricultural IoT, IAQ monitor, air conditioner with purifying function, air purifier, automotive and other consumer electronic products etc. 

Features

● Advanced non-dispersive infrared technology (NDIR) with independent intellectual property 
● High accuracy: temperature and concentration calibration within whole measurement range
● High stability: advanced auto-calibration in background
● Small size and compact structure and easy to install
● One beam for detecting, the other beam for reference

Applications

● Ventilation system
● Agricultural greenhouse facilities
● Agricultural IoT
● IAQ monitor
● Air conditioner with purifying function
● Air purifier 
● Automotive
