DS-CO2-20 Carbon Dioxide CO2 Concentration Sensor Module Indoor Environment Detection Authentic Dual Channel

Product Descriptions

DS-CO2-20 is a kind of digital NDIR sensor, which can acquire and calculate the concentration of carbon dioxide in the air continuously and

​output them in the form of digital interface. This sensor can be inserted into variable instruments related to the concentration of carbon dioxide 

in the air or other environmental improvement equipments to provide correct concentration data in time.

Product Main characteristics

 NDIR

 Two Channels

 Industrial-grade Precision

 Minuscule Size

Product Working principle

The sensor has one chamber and two receive channels that can get the signal of light intensity in the photoelectric element made by infrared 

light with two kinds of wavelength. Then the concentration of carbon dioxide can be calculated according to the carbon dioxide absorption 

function of the two kinds of wavelength.
