New Code Added

A project log for Gas Sensor For Emergency Workers

Gas sensor "grenade" that may save lives instead of taking them. The sensor can be thrown into dangerous areas to remotely report levels

Thanks to everyone for supporting this project! I'm really happy it made the top 10 and will hopefully make a difference in the world.

As I mentioned before in the project, the MQ2 sensor is great for a "proof of concept" but needs to be updated to a full sensor suite to replicate industry gas analyzers. One problem I have had is that when the sensor is flooded with a gas like LPG- it false triggers on the remaining ones whereby relaying potentially incorrect levels.

This isn't a huge deal for basic project sharing but I decided to simplify the code to a basic "Go" or "No-GO" indication. This would trigger anyone to be ready for all 3 situations if alert is indicated.

New code is added to GIT with a simple annunciation- it repeats safe if all are 0 levels and repeats "Alert" 3 times any time there is any indication of levels above zero from the sensor.

I really wish I could afford to get a proper sensor system but in the interim this is one more option to take the project forward.

I will try to do a final update video soon covering some "insider info" as to why I truly love this project and why I wish I could have used it in daily work for many years. It does indeed apply to many fields of industry and I can't believe a commercial unit like this is seemingly not yet available.

Enjoy!
