AC Sensor for arduino with Optocouplers

#electronics #diy This is about making AC sensor with optocouplers. This can be used in arduino projects to detect the Alternative Current to be detected. This can be caused to electric shock if you touch AC side but, the other side is safe from AC.

If you want, you can use this any other projects than arduino projects. I have given all the required diagrams in this video.
