Hazardous Gas Monitor

Build a portable gas monitor to check for dangerous levels of hazardous gases in your home, community, or on the go and prevent your friends from lighting a cigarette during a gasoline fight. Please note that this is solely a movie reference gasoline fights should probably be avoided in real life. This tutorial shows you how to build a web-connected canary monitor for three hazardous gases: Liquid Propane Gas (LPG), Methane (aka natural gas), and Carbon Monoxide (CO). Using the Particle Photon microcontroller, the sensor readings are converted into parts-per-million (PPM) and uploaded to the data.sparkfun.com web service.”
