    Default Help!!! PicoBoo Ankle Tickler on Motion Sensor - not working

    I am running a PicoBoo Fl-104s to an ankle tickler with a 1/2 inch high flow valve, and attempting to trigger with IR motion sensor. Everything works fine with a regular solenoid, but when I hook up the 1/2 in high flow valve, the motion sensor flashes and keeps triggering. It does not do it with smaller solenoid valve, and I have reset to normally open and closed on the PicoBoo. Is it getting interference from the larger solenoid maybe? Do I need to add a diode? Power supply is 12v1amp and I got everything from FrighProps. It works fine and triggers the solenoid, just keeps repeating the recorded sequence and never goes off? I do let the sensor warm up, and if I unplug one wire from the solenoid and plug everything else in, it's all good. It runs through the sequence once or twice and shuts off. But as soon as I touch that other wire to trigger the solenoid it never stops running the sequence, like the sensor is getting triggered somehow? Any help would be appreciated, Thanks.

    You could try a diode, I've had interference from 12VDC solenoids in the past. The solenoid kept triggering some ISD ChipCorder boards I was using. They're sometimes worse than large relays when the power switches off. I used a 50V, 3A rectifier diode that I got at Radio Shack. The diode ring should face the V+ terminal of the solenoid coil. Good luck!

    Thanks, I think I will go by and grab a diode to see if that helps me out.

    Diode didn't solve it. I'm going to try a bigger power supply and see if that does it (as another poster suggested on hauntforum)
