Description
MQ-3 Gas Sensor Module This is the MQ-3 Gas Sensor Module, which is simple to use. It can sense the presence of Alcohol in the air. The module uses our MQ-3 sensor. 1? header pins. MQ-3 gas sensor provides an analog output corresponding to the concentration of the gas in the air and an easy-to-use digital output. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air.
Its conductivity increases as the concentration of alcohol gasses increases. It has a high sensitivity to alcohol and has good resistance to disturbances due to smoke, vapour and gasoline. MQ-3 gas sensor module provides both digital and analog outputs. It can be easily interfaced with Microcontrollers like Arduino Boards , Raspberry Pi etc.
This MQ-3 alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. The sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor.
