A Hybrid Gas Sensor based on Infrared Absorption for ...

Abstract— A hybrid gas sensor based on infrared absorption has been developed for indoor air quality monitoring. The sensor is used to measure the concentration of carbon dioxide (CO2) and carbon monoxide (CO) to 1 part per million (ppm) level in indoor environment. Photoresistor PbSe was used as a sensor in order to measure two gases at the spectrum absorption band of µm and …
