Trax of Elektronika.ba has written an article detailing his inductive loop detector that uses PIC microcontroller and Colpitts oscillator with a large coil buried in pavement to detect vehicles: Inductive Loop Detector works by detecting an inductance change in wire loop (coil) that is buried in road. It does that by measuring the frequency of the internal […]

Simple Arduino EMF detector
Here’s a simple Arduino EMF detector by Aaron ALAI: This is an improved version of an Arduino EMF detector from Aaron ALAI. It uses one resistor and a piece of wire to detect if there is any EMF (elector-magnetic field) around. Nice and simple idea! Via PCBheaven.
