WebFeb 14, 2024 · How Does an H2S Detector Work? Hydrogen sulfide gas detectors primarily use electrochemical sensors to detect and measure parts-per-billion (‘ppb’) and parts-per-million (“ppm”) levels of H2S gas. These sensors depend on a highly reliable electrochemical reaction that occurs when H2S gas combines with specific materials used in the sensor. WebMQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It …
