Summary of Content
When a metallic object passes near the coils, it disrupts the balance, inducing a small readable voltage in the Rx coil.
The enduring value of Overton and Moreland's work lies in its accessibility and engineering integrity. It strips away the proprietary marketing jargon used by commercial manufacturers and exposes the raw physics and analog circuit design principles beneath the plastic housing. For anyone looking to move past pre-made modules and truly engineer custom sensing equipment, this text is an indispensable resource. This public link is valid for 7 days
