Just the item I was looking for and it works great
For AC mains/ Zero Crossing Detector
I was looking for a way to detect a/c voltage to determine when power goes out in my house and to tie this in with my home automation system. I found plenty of current sensors and a few for DC voltages but nothing else for AC. I didn't really want to use a relay as some get warm if they are on constantly. This is exactly what I needed. Simple to connect and get working and the response is instant. Thank you!
