I have got a motion sensor which drives the coil of a small 230 VAC relay. This relay switches a transformator+rectifier for several garden lights at 12 VDC.
Whenever the coil is de-activated (motion sensor's end of signal, a set time), it sends spikes back into the motion sensor which resets it and makes it do strange things.
I'm more mechanical minded, but need some help with this one. Would a R and a C put parallel over the coil help this?
If so, could someone point me to where to find the necesssary info to calculate the values of both, or is there a rule of thump to do so?
many thanks in advance...
