Inductive Loop Detector - Project published

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 oscillator which powers the mentioned coil. When a metallic object moves over the coil it changes its inductance and that in turn changes the oscillator frequency which is measured by the microcontroller.

It is used for vehicle access control at door and barrier controls, for monitoring the occupancy and for vehicle counting in parking garages, traffic light installations and traffic controllers, direction and speed detection of vehicle traffic (if dual channel version is used), in car-wash plants, etc.

Just wondering if the project is still available anywhere? I'd be very keen to build my own! Thanks!!

Hello!! This looks like awesome project to build. You have done amazing job in putting together entire project with details. Thanks a lot....I have been building small things using arduino kit. Have never got any PCB manufactured. Could you kindly suggest where/how can I get PCB done? Best wishes!

How much is = also add letter "a" at the end of your result! Eg.: 7a
