MQ-5 – Gas Sensor Module

23.00

The gas sensing material used in the MQ-5 gas sensor is tin dioxide (SnO2), which has a low conductivity in clean air. When there is flammable gas in the environment where the sensor is located, the conductivity of the sensor increases with the increase of the flammable gas concentration in the air. The MQ-5 gas sensor has high sensitivity to butane, propane and methane, and can take into account both methane and propane. This sensor can detect a variety of flammable gases, especially natural gas, and is a low-cost sensor suitable for a variety of applications.
