Description

This is circuit schematic diagram of Metal Detector Based on TDA0161 Proximity Detector IC that can help you to build meteal detector circuit in this time. The main component in this circuit are TDA0161 IC and inductor to sense. 

According Electronichub site that also published this circuit describe that TDA0161 Proximity Detector IC: TDA0161 is a Proximity Detector IC manufactured by STMicroelectronics. It can be used detect metal objects by detecting the slight changes in the high frequency Eddy current losses.

The TDA0161 IC acts as an oscillator with the help of externally tuned circuit. The changes in supply current will determine the output signal i.e. current is high when a metal object is near and it is low when there is no metal object.

TDA0161 has 8 pins and it comes in Dual in – line Package (DIP). The following image shows the pin diagram of TDA0161 IC.
