Help! Where are my Sprinkler Valves Located?

Step 4 More Pictures of the Completed Project

At the control panel for you sprinkler system disconnect the wires from the switch that control the valve you are trying to locate. Insert the Sprinkler Valve Finder inline. The circuit basically is taking place of the control panel switch. Once connected turn on your sprinkler system like normal (remember to turn off the water first). Now flip the SPST toggle switch on the circuit. Your valve will not turn on and off at the same rate the LEDs on the board are flashing. Go out into your yard and start listening.

ANyone got a schematic for the thing that has a speaker on it ( I am not sure what its called ) that makes a sound the closer you get to the valve your trying to find. Its basically a detector that magnifies the sound through the speaker like a homing reciever.

Perhaps not a good idea to use a reed relay to handle the solenoid's current.

They are cheap, fit the specs, and it works. Please teach this amature a thing or two and explain why another relay would be a better choice for this project.

I'm not an amature, I have built many a circuits in my life. I was only saying that the reed relay might not be able to handle the solenoids current, because you might not know the solenoid's current unless you measure it. So if you measured the solenoid's current then chose a suitably rated relay for the job, that's the point I was trying to get across to you.It was only a suggestion.

He was talking about himself.

thanks for the info. Its a good point that the size the relay should be sized to the solenoid's current.
