Gas Sensor
A gas sensor is used to detect the presence or concentration of gases in the atmosphere. There are different types of gas sensors depending on the sensing element used to make the sensor. The type of sensing element determines the type of gas that the sensor is able to detect. The various gases that can be detected using gas sensors include methane, butane, LPG, Smoke, alcohol, ethanol, CNG gas,hydrogen, CO2, Ozone, Ammonia, Natural gas and Carbon Monoxide. Gas sensors are mostly used in industries or households to detect concentration of toxic gases. They can also be used to detect the quality of air or emergency incidents like gas leaks.
