ADIY MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in 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 come in contact with the gas. This change in the value of resistance is used for the detection of gas.
ADIY MQ2 is a metal oxide semiconductor type gas sensor. Concentrations of gas in the gas is measured using a voltage divider network present in the sensor. This sensor works on 5V DC voltage. It can detect gases in the concentration of range 200 to 10000ppm.
This sensor contains a sensing element, mainly aluminium oxide-based ceramic, coated with Tin dioxide, enclosed in a stainless-steel mesh.
