Alcohol gas sensor - SparkFun Electronics

11/02/2009· Alcohol gas sensor #59948. By rootbeer - Tue Nov 25, 2008 10:24 am - Tue Nov 25, 2008 10:24 am #59948. I just received the alcohol gas sensor and breakout board. Soldered it together connected H1 to vcc and ground to ground of course. A1 to vcc and A2 to a 100k resister, and the resistor then to ground. Then I connect a wire from A2 to the analog input. This setup is identical to …

MQ-3 Alcohol Sensor Module Pinout, Datasheet & Other Gas ...

07/10/2018· MQ-3 gas sensor has high sensitity to Alcohol, and has good resistance to disturb of gasoline, smoke and vapor. This sensor provides an analog resistive output based on alcohol concentration. When the alcohol gas exist, the sensor’s conductivity gets higher along with the gas concentration rising. There is a resistance across an A and B inside the sensor which varies on detection of alcohol. More the alcohol, the lower the resistance. The alcohol …

Alcohol Level Meter using Arduino & MQ-135 Alcohol/Gas Sensor

12/05/2020· The alcohol/Gas sensor we used is the MQ-135 sensor. This is a sensor that is not only sensitive to alcohol, particularly ethanol, which is the type of alcohol that is found in wine, beer, and liquor. Instead of MQ-135, you can use MQ2, MQ3, MQ5 module as well. Basically, they all have similar functions. This type of sensor circuit can be used as a breathalyzer to check a person’s blood ...
