Product description: Grove - alcohol sensor - MQ3 - semiconductor.

Module with sensor MQ3 for detecting alcohol vapour and its concentration. The sensor iscompatible withArduinoand Raspberry,thanks toGrove connector it is possible toconnectdirectlytoGrove-Pi+ andGrove BaseShield.The sensorcommunicates through the analog interface, so in orderto use it with Raspberry it is required to use Grove-Pi+ overlay orADC.There is a potentiometer on the board to adjust the sensitivity.

Arduino compatible product

The manufacturer providesa user guideshowing its connection and programming.

Alcohol sensor connection - MQ3

The PCB is equipped witha 7-pin bracketso that the replacement of the sensor itself is non-invasive and can be simply removed. The board has a built-in Grove socket that allows direct connection of the sensor to Grove-Pi+or GroveBase Shieldcovers.Due to the analogue communication interface, the sensor cannot be connected to the Raspberry without using the Grove-Pi+ overlayorthe ADC.
