With COVID, we are home a lot more. We were curious how this was affecting our oil usage. We have a 275 Gallon vertical tank. It has an extra 2" vent hole on the top of the tank. I designed and 3D printed an insert to hold a sensor. The information and alerts can be sent to your cell phone. It works with IFTTT and Blynk.
wow, great project and what a nice math session you had!
I like the 3d printed cap, very very cool the way you did that.
oh and welcome to the community! I hope we can see you around very soon.
