Metal Detector Sensor Module

The Metal Detector Sensor Module operates on the principle of electromagnetic induction to identify metal objects. This module is composed of a transmitter coil that creates a magnetic field and a receiver coil that senses variations in the magnetic field triggered by nearby metal.
When a metal object nears the sensor, it disturbs the magnetic field, prompting the sensor to produce an output signal that indicates metal presence. These sensors are versatile, finding applications in security systems, industrial automation, and various hobbyist projects. The output can either be digital or analog, with some models offering depth detection capabilities.
This LC Metal Detector is designed for non-contact metal induction detection. It emits a sound when approaching any metal object. The module functions by inducing currents in metal items and responding accordingly. An integrated buzzer alerts users upon detection, and an onboard potentiometer allows for sensitivity adjustments.
Users will need to solder the power connections for the Metal Detector Sensor Module to operate correctly, with the positive lead connected to the module’s exterior and the negative lead positioned between the potentiometer and an electrolytic capacitor.

Features:

  • “V+” ? Connect to the positive power supply
  • “V-” ? Connect to the negative power supply
  • Utilise the potentiometer to adjust detection range and strength.
  • Compact and user-friendly design.
  • Includes a buzzer for metal detection alerts.
