## Overview

The Robocraze Metal Detector Sensor Module is a compact, non-contact metal detection board operating at 3-5V, designed for seamless integration with popular development platforms like Arduino and Raspberry Pi. Featuring a 10cm detection range, adjustable sensitivity, and an onboard buzzer for instant alerts, it’s ideal for DIY security, robotics, and automation projects seeking precise and customizable metal sensing.

## Description

Package includes 1 quantity. Our can use this lace metal detector non-contact metal induction detection module as a metal detector. When it approaches any metal, it makes a sound. This is a module specifically designed to detect metal. The module operates by inducing currents in metal objects and responding when it occurs. A nice onboard buzzer signals when it detects something and an onboard potentiometer allow adjustment of sensitivity. The power cables of the metal detector non-contact metal induction detection module will need soldering on for the module to function, positive to the outside of the module and negative between the potentiometer and an electrolytic capacitor.

## Features

- Non-Contact Metal Detection : Detects metallic objects within a range of up to 10cm using electromagnetic induction sensing technology for reliable proximity detection
- Wide Voltage Compatibility : Operates on 3V to 5V DC supply, making it compatible with Arduino, ESP8266, Raspberry Pi and other embedded development boards
- Adjustable Sensitivity Control : Built-in potentiometer allows fine tuning of detection range for different applications including security and automation systems
- Onboard Buzzer Alert System : Provides instant audible indication when metal is detected, making it ideal for real-time detection and alarm-based projects
- Compact DIY-Friendly Module : Small PCB design suitable for robotics, smart security systems, industrial automation and educational electronics experiments
