MQ-3 gas sensor (alcohol) for Arduino is an analog gas sensor and can detect the presence of alcohol vapors in the air, or by breathing in the perfume or alcohol.
the output of MQ-3 gas sensor (alcohol) is an analog signal proportional to the alcohol content around the gas analyzer. The sensitivity can be adjusted using the trimmer on the sensor board.
The analyzer built-in heating element, which is required for the chemical reaction. Therefore, while the sensor is hot. To obtain a stable reading new sensor must be warm once (leave enabled) within 24 hours. After that, after the stabilization will take about a minute.
Reading MQ-3 gas sensor (alcohol) for Arduino are affected by temperature and humidity. Therefore, in the case of MQ-3 sensor in a changing environment, with the need to obtain accurate readings, you will need to implement the payment of these parameters.
