Description

Electronic circuit schematic like in Figure 1 above is  Circuit Schematic 220V Live Wire-in-Wall Scanner using FET. This is little circuit will help you to scan the line of a 220V live wire in the wall. The FET gate is connected to a capacitive metal sensor (which is usually a simple metal plate). When you hold the sensor close to the wall, the LED will indicate the current flow around where it detects the wire. Works on 9VDC.
