How to make alcohol sensor with the help of Arduino uno
There are different kinds of sensors available in the MQx Series of sensors, where x is defined as 1,2,3,… and so on.
The x differentiate each sensor as per its sensing capability, for example,:
- MQ6 is used for sensing the LPG and
- MQ3 is used for sensing the Alcohol.
So explore the MQ3 sensor, try to understand, and also help the community here to know about:
- its structure,
- how it is made,
- Chemistry to Electrical signal output
- how it works,
- how to use it.
