Did a quick search and didn't see anything that really stood out. What I would like to do is sense when my sump pump turns on and off. One way I was thinking of doing this is by sensing when the current draw on the AC line went up and down.... something like an AC clamp meter (out of the AC circuit and non-distructive). Is there a device out there that I can do this with and be able to interface to a pic? Don't need a high resolution output, just something to indicate there is current draw past the idle threshold... assuming there is a small amount of current draw in the idle state. Any enlightenment would be appreciated. Voltage = 120V 60 Hz .Thanks
