  13. I need a current sensor (On/OFF) for a standard 110 AC line which
  14. gives a logic signal (5V).  I tried running the live line through a coil
  15. which I ripped out of a small transformer and then amplify the coil
  16. response w/op amps but I could not get this to work.
  17.  
  18. If anyone has any suggestions they would be much appreciated.

  20. Thank you.
