Hi,
I'm creating my own PI detector and I'll try to make some discrimination between ferrus and non-ferrus metals but I don't know how to get many sample points from the received signal to compare the voltage. I've read some articles for such discrimination but don't know how to achieve it. If anyone can help me I'll be very grateful.
