Which sensors are used in gas detectors? - SEMA Gases

Infrared (IR) sensors. With infrared sensors, hydrocarbons and other infrared active gases such as water vapour and CO2 can be detected. An infrared sensor uses radiation passing through a known volume of gas. Energy from the sensor beam is absorbed at specific wavelengths depending on the properties of the specific gas. The energy in this wavelength is compared to a wavelength outside of …

Infrared detector - Wikipedia

An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. Bolometers and microbolometers are based on changes in resistance. Thermocouples and thermopiles use the thermoelectric effect. Golay ...
