Product Description
The Metal Detector Module is a "plug-and-play" solution for identifying ferrous and non-ferrous metals. It features an onboard potentiometer that allows users to fine-tune the sensitivity and detection threshold, ensuring it can ignore small metallic interference while focusing on target objects. The module is compact and breadboard-compatible, featuring a standard 3-pin header (VCC, GND, OUT) that connects directly to an Arduino, Raspberry Pi, or any microcontroller without the need for external voltage dividers or complex circuitry.
Key Features
Non-Contact Detection: Reduces wear and tear as the sensor never needs to touch the object it is detecting.
Adjustable Sensitivity: The multi-turn trimmer allows for precise calibration based on the specific metal type (Iron, Aluminum, Copper, etc.).
Real-time Feedback: Includes a built-in LED that glows instantly when metal is detected, simplifying the debugging process.
Low Power Logic: Designed to work on 3.3V and 5V systems, making it compatible with modern IoT boards like the ESP32.
Wide Application: Suitable for industrial limit switches, metallic material sorting, and DIY treasure hunter prototypes.
