CO2 Absorption Spectrum.

Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of wavelengths, which are , and 15 micrometers (µM). This means that most of the heat producing radiation escapes it. About 8% of the available black body radiation is picked up by these "fingerprint" frequencies of CO2.


CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 01% (010,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
