Mq 3 Alcohol Gas Sensor

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.

Mq 3 alcohol gas sensor.

The two pins a h are used for the heating purpose and the other two pins are used for the ground and power. The alcohol sensor we will use is the mq 3 sensor. This fits your. Only 2 left in stock order soon.

Contempo views mq 3 alcohol ethanol gas sensor module pack of 4. Make sure this fits by entering your model number. The mq3 gas sensor has a very hight sensitivity to alcohol gas. This is a sensor that is not only sensitive to alcohol particularly ethanol which is the type of alcohol which is found in wine beer and liquor.

Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. It is suitable for sensing alcohol gas concentration. Fig 4 is shows the typical dependence of the mq 3 on temperature and humidity. When the target alcohol gas exist the sensor s conductivity gets higher along with the gas concentration rising.

Due to its high sensitivity and fast response time measurements can be taken as soon as possible. Sensitive material of mq 3 gas sensor is sno 2 which with lower conductivity in clean air. The grove gas sensor mq3 module is useful for gas leakage detection in home and industry. 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.

Mq 3 gas sensor. Rs sensor resistance at various concentrations of gases. There is a heating system inside the sensor which is made up of aluminum oxide. 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.
