Hi,
I have set up a deterrent to try and stop fuel thefts. I have a normal 240V PIR motion sensor, which is live, then activates a blue strobe light and two small buzzers. In between the PIR and the strobe/buzzers is a AC/DC converter which takes voltage down to 12 volts. The strobe light uses 180 ma and the buzzers even less. All works well but my problem is that when the PIR switches off there is still enough residual current to activate the buzzers continually and make the stroble light flicker occasionally. Presumably this is because the PIR is always having a small output? What do I need to do? Put something between the PIR and the strobe/buzzers? Novice here so all help appreciated! Thanks in anticipation
