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. Featured By RoboticsBD.

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

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.
