Would you consider a fuel tank sensor like these? Only the float is in the tank, all the electronics are outside.
My guess he wants to know before the level goes lower.
Drilling holes in the tank will certainly void a warranty.
How about security camera and with alarm output based on motion in specific area
I was in the same boat of requirements. Have not found any sensor as such that does the job. While searching I found out this sensor (https://www.ebay.com/itm/254206672470 (https://www.ebay.com/itm/254206672470)). Dont know if anyone has tried it?
Can anyone help me create an alarm for the truck's diesel tank?
It'd be a snap if you could hack into the truck's own fuel tank system. If the engine's off and the fuel level is dropping...
