This is a very easy to use low cost semiconductor Gas sensor Module with analog and digital output. This module uses MQ6 LPG gas sensor as a gas sensing element. It requires no external components just plug in Vcc & ground pins and you are ready to go.

For Digital output the threshold value can be easily set by an on-board potentiometer. Using this module you can easily interface MQ6 LPG gas Sensor to any Microcontroller, Arduino or even Raspberry Pi.

Features of MQ6 LPG Gas Sensor Module:-

• High Sensitivity to LPG, iso-butane, propane
  
• Small sensitivity to alcohol, smoke
  
• Good sensitivity to Combustible gas in wide range
  
• High sensitivity to Propane, Butane, LPG and also response to Natural gas
  
• Long life and low cost
  
• Simple drive circuit
