I am looking for a sensor or electronic regulator that can be coupled to a CO2 gasbottle.
I want to measure how full the bottle is. I will then link this with Arduino to an app that will tell me when its close to empty so I can replace the bottle.
I have looked on the internet but I am seeing that people are saying it is unsafe to couple sensors to a C)2 bottle.
My knowledge is very limited and any help will be appreciated.
