I had a brilliant idea to use half of my mimo2 to monitor the water sensor with the input and turning it off using one of the relays. Breaking one of the sensor wires. I worked all day to find out the water sensor is 24v ac, However when testing it the sensor when the ordinary 2 wire sprinkler sensor everyone hasA opens the circuit it doesnt let go off all the voltage hanging on to anywhere from 14-21 volts. This making it impossible to use on a pilot relay to see if sensor is open and not going to allow sprinklers to run.
I thought well maybe its my 3 year old sensor the micro switch is getting bad. Went bought a brand new one to find the same thing.
Anyone know of a water sensor that is truley open/close? Tried the Hunter mini-click and Orbit 91069 both just simple 2 wire open/close sensors but when they open they dont open all the way.
This project was going to be sweet, I was going to be able to check the system to see if it turned of naturally by the rain and if not I could do it. Turning it off and on is easy but monitoring the natural rain sensor is the problem.
