FS00302 Carbon dioxide sensor module Gas concentration detection CO2 module Probe element

1.Product overview

1.1 Detection principle

The non-dispersive infrared (NDIR) principle is used to detect the presence of CO2 in the air. When infrared light passes through, the intensity of light transmitted by CO2 molecules at a particular wavelength is significantly reduced, the degree of intensity attenuation being dependent on the gas concentration, the relationship between the two following the Lambert-Bier law.

1.2 Product description

FS00302 is an intelligent carbon dioxide gas sensor that combines NDIR detection technology with optical circuitry and circuitry to give excellent selectivity and no oxygen dependence. Long service life and stable data output; supports digital output and analogue voltage output for ease of use.
