MQ-2 Gas sensor Module

Description

This module is ideally suited to adding smoke sensing to your project. This is a detection module which can detect smoke particles to trigger a switch like response. This allows you to replace those mechanical switches that have been holding back your project all this time with something a little smellier.

An onboard potentiometer allows you to adjust the trigger volume so that you can tailor sensitivity to account for the projects surrounding background levels.

As a simple module it will suit use within a large range of projects based on microcontrollers such as Arduino boards and the Raspberry Pi. The module has a M3 mounting holes allowing for its easy attachment to a multitude of surfaces.
