It's just a simple metal detector circuit.

Next time you are down at the airport just ask:

"Hey guys, do you have the schematic of this thing? ... If so, can I have a copy please?"

Hi Vikas, welcome to the forum.

Chemelec has the voted best design, but it is certainly not for beginners.

Otherwise the simplest one is the 1-inch ranged one, see this from Z-X metal. You can buy the components or buy the whole thing by itself.

the link provided should be good for a few feet, I think 30 cm should be covered.

You don't need anything as complex as the first two circuits and the ZX circuit is not very sensitive with a small inductor as the sensor.
You need something like this. The coils are 15cm diameter and the circuit will detect a coin at 15 cm.

hi Colin, how much is the quality of the detection? It looks much simpler too.
