Gas Sensor ( MQ3) - Alcohol - Grove ↵ The Grove MQ3 Gas Sensor module is useful for gas leakage mq3 detecting ( in home and industry). 1 g/ dL mq3 is equivalent to 10000 ppm. Sensor MQ3 datasheet circuit , cross reference application notes in mq3 datasheets pdf format. MQ3 Gas Sensor Module The MQ3 gas sensor mq3 is alcohol sensor which is used to detect the alcohol concentration on your breath. A simple interface could be a 0- 3. In mq3 this tutorial I' m demonstrating how mq3 to use MQ- 2/ MQ- 5 gas sensors with Arduino. Datasheets: MQ- 2: https:.
const int MQ3_ A_ Inputs = 0; / / the AOUT pin of the alcohol sensor goes mq3 into analog pin A0 of mq3 the arduino const int MQ3_ D_ Inputs = 8 ; / / datasheets the DOUT datasheets pin of the alcohol sensor goes into digital pin D8 of the arduino. It can detect Alcohol Vapour. According to module its datasheet, the MQ- 3 alcohol sensor detects 25 to 500 ppm datasheets of alcohol ( ethane). The Grove - Gas Sensor( MQ2) module is useful for gas leakage datasheets detecting( in home and datasheets industry).
