I’m looking for sensor to report empty space in a farm water tank
The environment is hot 100-150- Fahrenheit.
I like to have control when to add water when the tank it needed.
Empty parameter change, it is not specify level.
The water tank is 200 gallon
If the tank gets to 198galon, I like to add 1 gallon.
If the tank gets to 135galon, I like to add 5 gallons.
If the tank gets to 128galon, I like to add 11 gallons.
If the tank gets to 18galon, I like to add 15 gallons.
To add gallons are not a fix amount it depends on my request.
