MQ-2 Gas Sensor
The gas sensing material used in the MQ-2 gas sensor is tin dioxide (SnO2), which has 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-2 gas sensor has a high sensitivity to liquefied gas, propane, and hydrogen, and is also ideal for the detection of natural gas and other combustible vapors. This sensor can detect a variety of flammable gases and is a low-cost sensor suitable for a variety of applications.
