DS-CO2-20 CO2 Sensor

Main characteristics
 NDIR
 Dual wavelength
 Industrial-grade Precision
 Minuscule Size

Overview

DS-CO2-20A 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.

Working principle

NDIR gas sensor principle of work is according to the different gas molecules for absorption characteristic of near infrared spectra,by gas concentration and absorption strength relationship (Lambert-Beer law) analysis and determine the concentration of the gas. This sensor adopts the non-spectrophotometric infrared absorption principle and adopts the design structure of single air chamber and double receive channels, it has the characteristic of small structure and high detection precision.
