Description:

Sensitive material MQ-3 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). When sensor in alcohol steam environment, a sensor’s conductivity with the increase of alcohol gas in the air.Using a simple circuit to convert the change of conductivity and the gas concentration corresponding to the output signal. MQ - 3 to alcohol gas sensor sensitivity is high, can resist the interference of gasoline, smoke, water vapor.The sensors can detect a variety of concentration alcohol atmosphere, is a low-cost sensor suitable for many applications

Application:

Alcohol (ethanol), used for motor vehicle drivers, and other no drunken homework personnel on-site testing, also used in other places of ethanol vapor detection
