Hi, I am a All Circuits newbie and a DYI person with a modicum of electrical skills. I am having trouble finding a 12v AC motion sensor (PIR). PIRs are either 120v AC or 12v DC. Couple of questions:
* Any suggestions on where to buy a 12v AC PIR?
* If I start with 120v AC, I could use 120v to power a PIR and then use a tranformer to step down the PIR output to 12v. Any pitfalls?
Thank you,
Michael
