MQ2 Flammable Gas and Smoke Sensor Module

This is a very easy to use low
cost semiconductor Gas sensor Module with analog and digital output.
This module uses MQ2 Smoke & Flammable 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 MQ2 Smoke
& Combustible gas Sensor to any Microcontroller, Arduino or even
Raspberry Pi.

Since
this Gas Sensor module is sensitive to smoke it can be used in for fire
detection. MQ2 Gas Sensor is also sensitive to flammable/combustible
gasses like LPG, Propane & Hydrogen.

Specifications:-

• Power Supply: 5 Volts
  
• Interface Type: Analog & Digital
  
• High Sensitivity to Smoke & combustible gasses like Hydrogen, LPG & Propane.
  
• Low Cost.
  
• Stable & Long Life.
  
• On board Power indication.
