MQ2 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 contains a sensing material whose resistance changes when it comes in contact with the gas.
CO sensors of the FLOW EVO series from smartGAS are ideal for this task: They operate on the basis of nondispersive infrared (NDIR) absorption and therefore detect even minuscule carbon monoxide concentrations. The sensors are available for measuring ranges from 0 to 2000 ppm, 0 to 5000 ppm and 2, 10, 20, 50 and 100 Vol%.
