When connecting more than one loop to a detector, always connect the loops in series. The correct phasing of the loops is important if the loops are close to each other. The sensitivity setting on the loop detector should be increased when adding loops to the same detector. It is important to use the correct wire in your loop installation.

Here is the reference circuit diagram of a simple inductive proximity sensor, wired around the 8-pin proximity detector chip TDA0161. This monolithic integrated circuit (from STMicroelectronics) is designed for metallic object detection by sensing variations in high frequency Eddy current losses.

In this project, we are going to build a simple metal detector circuit using a BC548 transistor. Metal detectors generally come in one of three types: very low frequency (VLF), beat-frequency oscillation (BFO), and pulse induction (PI). Metal detectors operate by transmitting an electromagnetic field from the search coil to the ground.
