DESCRIPTION
This module is ideally suited to adding pollution sensing to your project. This is a detection module which can detect various gases ( NH3,NOx, alcohol, Benzene, smoke,CO2 ,etc) 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 M2.5 mounting hole allowing for its easy attachment to a multitude of surfaces.
