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.

Please feel free to post your query.
