GasSense is used to detect gasses, from alcohol and Carbon Monoxide to propane and other gasses. The module comes bundled with MQ3, sensitive to alcohol, ethanol and smoke. It is possible to replace MQ3 with any other sensor on the market, as long as the sensor heating element is 5V and it has the same standard pinout.


This module is designed with an on-board transistor to optionally control the sensor’s internal heat element. Through a 100K resistor divider the module returns an analog signal in accordance with the saturation of the air.
