The mq3 gas sensor has a very hight sensitivity to alcohol gas.
Mq 3 alcohol gas sensor.
It is a low cost semiconductor sensor which can detect the presence of alcohol gases at concentrations from 0 05 mg l to 10 mg l.
Alcohol in the clean air.
In this project we will go over how to build an alcohol sensor with an arduino.
Mq3 alcohol gas sensor mq3 gas sensor is a very easy to use and very handy sensor.
The sensitive material used for this sensor is sno2 whose conductivity is lower in clean air.
Gas detector sensor alcohol detection sensor for arduino raspberry pi.
When the target alcohol gas exist the sensor s conductivity gets higher along with the gas concentration rising.
The alcohol sensor we will use is the mq 3 sensor.
Sensor resistance at 0 4mg l of alcohol in air at 33 rh and 20 rs.
Waveshare mq 3 alcohol ethanol gas sensor module gas detector sensor alcohol detection sensor for raspberry pi by waveshare.
Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
The mq 3 alcohol gas sensor consists of a total 6 pins including a h b and the other three pins are a h b out of the total 6 pins we use only 4 pins.
Mq3 alcohol gas sensor can detect alcohol gas concentrations anywhere from 200 to 10000 ppm.
The two pins a h are used for the heating purpose and the other two pins are used for the ground and power.

Mq 3 alcohol sensor circuit built with an arduino.
Fig 4 is shows the typical dependence of the mq 3 on temperature and humidity.
Mq 3 module is suitable for detecting alcohol benzine ch 4 hexane lpg co sensitive material of mq 3 gas sensor is sno 2 which with lower conductivity in clean air when the target alcohol gas exist the sensor s conductivity is more higher along with the gas concentration rising.
The sensitivity of the sensor can be adjusted by using the potentiometer.
The grove gas sensor mq3 module is useful for gas leakage detection in home and industry.
Due to its high sensitivity and fast response time measurements can be taken as soon as possible.
