Carbon monoxide is an invisible, odorless, tasteless, and extremely toxic gas. You can’t detect it, but our sensors can for you. When this lifesaving sensor detects the presence of carbon monoxide, it will sound a highdecibel alarm and notify you on your mobile device.

In this study, lowcost electrochemical sensors manufactured by Alphasense Ltd. for detection of CO and oxidative gases (predominantly O 3 and NO 2) were evaluated. The voltages from three oxidative gas sensors and three CO sensors were recorded every sec when exposed to controlled gas concentrations in a 3 acrylic glass chamber.
