So Now my unit is able not just to beep 3X louder, but Also to control an automatic shutdown motor, this motor can automatically close the gas handle in case of a gas leak.
The good thing is that it doesn't need dismantling of the gas pipes, as it can easily be attached above the gas handle and fix it around the gas pipes with a metal bar, that's it!
We also were able to develop a smarter microprocessor firmware that prevents the gas leaks
