If you live in a remote area it is possible that you are not serviced by a mains gas connection. If this is the case you are probably relying on a propane tank. Wouldn’t it be great if you could reliably track the amount of gas remaining in your tank so that you could schedule a top up and not risk running out of gas?
This project from Julio Aguirre you can turn your propane tank into a solar powered IoT device that sends you up regular information about your propane tank. Not only does it provide you information but it also automatically emails or SMS’s your gas supplier to arrange a new delivery when you are running low. Even if you have a mains gas connection you could use this to keep track of the gas levels on your BBQ so that you never run out of gas at an inconvient time ever again!
