In this short tutorial I'm demonstrating how to calibrate an MQ-2 gas sensor and get your readings in ppm units. I'm assuming you don't want to spend hundreds of dollars for a calibration kit. The method shown in this video is based on a piece of Arduino code created and shared for free by a company called Sandbox Electronics.
