A quick overview of my gas sensor "grenade" I created using an Arduino nano, MQ2 smoke, LPG and CO gas sensor.  It reads the levels and transmits them out in voice to any receiver.

Entire project doccumented here:

I will do a future build video showing the build and code in detail.  This was a really fun video and maybe could help save lives someday.  Gas sensors are traditionally very expensive and I have never seen one designed to be tossed into an unknown environment and heard remotely (also at a low price)
