Great article and idea! Minor tweak to this… there isn’t even a need to rewire the sensor etc. You can just put it in the whole foreseen on these gas meters as depicted in the picture… Th cool thing of this sensor is that it has a small “hook/edge” on the board which allows it to lock into place.
This is the “hook/edge” that I’m talking about…
This makes it easy to install! Just remove the plastic shell et voila!
