What's that smell? It's noxious gas of course! If you're in an environment where there's a possibility of gaseous release of which you'd rather not breathe, why not build an automatic system for sensing and alerting you? The design for the Environmental Alert System is driven by my motivation to understand the concentrations of different chemicals in the air. The unit consists of an array of four gas sensors (one each for methane, propane, carbon monoxide, and smoke) connected to an Intel Edison for wireless detection and alerting. While no substitute for a proper commercial chemical detection system, the EAS makes for a great weekend project!
