PIC Based Cable Tracer

You all know what a cable tracer is, and if you don’t let me give you a quick info: a cable tracer is a tool that helps you detect cables hidden behind walls or underground. It’s a goo idea to avoid damaging cables so this kind of devices are widely used in the industry.

The system works by injecting a 125-kHz signal into an underground cable. A pick-up coil receives a sample of the field. The field’s strength indicates the presence and direction of a cable. Simple ! now all you have to do is build it.
