Gas sensor based on gas MQ-3 can detect the presence of alcohol vapors: from perfume or alcohol, in the air or breath.
Outcome is an analog signal proportional to the content of the spirits around gas. Sensitivity can be set using the trimmer on board sensor.
In the device has a built-in heating element, which is required for the chemical reaction. Therefore, during operation, the sensor will be hot, it's OK. To obtain stable readings new sensor warm up once (on leave) during the 12:00 am. After this stabilization after inclusion will take about a minute.
Sensor readings are influenced by temperature and humidity.
