Hi All, I was wondering today if it would be at all possible to make a tiny metal detector device, no bigger than an inch squared or even smaller?
I wouldn't know where to start in terms of the type of sensor that I would need, but it came about by an app on my iPhone, where you can utilise the magnetic sensor in the phone to turn it into a metal detector. It measures the magnetic field and alerts you when this increases to a significant value. Obviously, this isn't entirely accurate but is a good start.
Has anybody had any past experience with certain types of sensors that might be useful for me to play around with.
Many Thanks
