Adding Safety Automation

So the device has been in testing for several months, it is worked fine at first, but then it started showing false alarms!

So we need to rework on it again
It also doesn't have automation for safety, so we thought of lets working on that too.

I believe I should add a motor to make it shut the gas valve handle shut down automatically in case of a leak. However, this means redesigning everything from electronics to plastic casing.
