Gas sensors with Arduino - July 21, 2014
Description:
In this tutorial I'm demonstrating how to use MQ-2/MQ-5 gas sensors with Arduino. These little devices may be used in gas leakage detectors. The MQ-2 is suitable for detecting LPG, i-butane, propane, methane, hydrogen and even smoke. The MQ-5 detects LPG, natural gas and town gas.
