Water Level Switch
I want a simple 1/0 output to switch off a heating/cooling circuit if the water level drops below a certain level.
I want my raspberry pi 3 to return a 1 or 0 indicating that my water level is above or below a certain point.
I want to do this by having 2 copper wires stuck to the wall of my system, with the water completing the circuit. If the water goes below the level, making the circuit incomplete and outputting a different integer.
I want to know if this is possible using my current setup.
The will light up when the water level drops below.
