2 Pack MQ-3 Special Alcohol Ethanol Gas Sensor Module
2 Pack MQ-3 Special Alcohol Ethanol Gas Sensor Module
Description
MQ-3 gas sensor is sensitive material used in clean air, low conductivity tin dioxide (SnO2). When the sensor is present in the environment in which the alcohol vapor, the sensor's conductivity increases with the concentration of alcohol gas in the air increases. Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal. MQ-3 gas sensor with high sensitivity to alcohol, gasoline can resist, smoke, water vapor interference. This sensor can detect various concentrations of alcohol atmosphere, is a low-cost sensors for a variety of applications
