Description

MQ138 Organic Vapor Sensor Conductivity In Clean Air

The gas sensing material used in the MQ138 gas sensor is tin dioxide (SnO2), which has a low conductivity in clean air. When there is organic vapor in the environment where the sensor is located, the conductivity of the sensor increases with the increase of the organic vapor concentration in the air. The change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit. The MQ138 gas sensor has high sensitivity to toluene, acetone, ethanol, formaldehyde, and is ideal for monitoring hydrogen and other organic vapors. This sensor can detect a variety of organic vapors and is a low-cost sensor suitable for a variety of applications.
