Interfacing Gas Sensor (MQ2) With AVR
After basic peripheral interfaces with AVR, it's time to interface some sensors with it. In this tutorial we will interface Gas sensor MQ2 with Atmega 32 breakout. We will require a Gas sensor (MQ2) breakout .
Basics
The gas sensor MQ2 suitable for detecting of LPG, i-butane, propane, methane, alcohol, Hydrogen, smoke etc. It is highly sensitive and gives fast response due to this we can take measurements as soon as possible.
