Product Name:
Metal Detector Sensor Module – Non-Contact Inductive Proximity Sensor

Overview:
The Metal Detector Sensor Module is a high-sensitivity inductive sensing device designed to detect metallic objects without any physical contact. It operates using electromagnetic induction, allowing it to sense both ferrous and non-ferrous metals within an approximate range of 1 to 5 cm, depending on object size and sensitivity settings. This module is ideal for building metal detection projects, security systems, treasure-hunting tools, industrial sorting machines, and robotics applications. Its plug-and-play design makes it easy to integrate with popular development platforms such as Arduino, Raspberry Pi, ESP32, and other microcontrollers.

Key Features:
This sensor provides accurate non-contact metal detection, which improves durability by eliminating mechanical wear. It includes an onboard buzzer and LED indicator that activate instantly when a metal object is detected, offering clear audio and visual feedback without additional components. An adjustable multi-turn potentiometer allows precise tuning of the detection sensitivity, making it adaptable for detecting different metal sizes and distances. The compact and lightweight design ensures it fits easily into handheld devices, robotic chassis, or compact enclosures. With a simple 3-pin interface consisting of VCC, GND, and Signal, the module enables quick wiring and straightforward programming for fast project development.
