Using a MQ series gas sensor, this module easily adds alcohol detection to your project. An analogue output can be used to monitor changes in alcohol concentration, while a digital output is triggered when the concentration exceeds a pre set threshold. Build your own breathalyser or automate your home-brewing, or create an alcohol controlled car lockout. Adjustable sensitivity.
