· Characteristics of a Good Indoor Air Quality Monitor. The first characteristic to check for in an air quality monitor is its accuracy. Accuracy can mean many things for air quality monitors. For one, monitors should be able to report the correct concentration of whatever gas or pollutant is trying to be measured. Second, the device should also not report erroneous readings or false-positive ...
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 …
