Product Description:

MQ-3B Semiconductor Alcohol Sensor For Portable Alcohol Gas Detector

Features:

Gas-sensitive material used in the MQ-3B alcohol sensor is tin dioxide (SnO2), which has a low conductivity in clean air. When alcohol vapor exists in the environment of the alcohol sensor, the conductivity of the gas sensor increases with the increase of the concentration of alcohol gas in the air. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of that gas.

MQ-3B semiconductor alcohol sensor has high sensitivity to alcohol and can resist interference from gasoline, smoke and water vapor. This gas sensor can detect a variety of alcohol atmospheres and is a low-cost sensor suitable for a variety of applications.

Product advantage

Good sensitivity to alcohol gases

Long life, low cost

A simple drive circuit is enough
