Metal Detector Sensor Module

Add intelligent metallic object tracking to your automated machines with the premium Metal Detector Sensor Module. Engineered for reliable non-contact detection, this high-performance sensor board uses an integrated, multi-turn inductive proximity coil to generate a localized electromagnetic field. When any magnetic or non-magnetic metallic element (such as iron, copper, aluminum, or brass) enters its detection field, the circuit senses the field disruption and triggers an instantaneous output signal. The breakout carrier board features an onboard LM393 voltage comparator alongside an adjustable trimmer potentiometer, allowing you to calibrate the sensitivity threshold and detection distance up to several centimeters. Operating on a standard 3V to 5V DC power envelope, it serves as the definitive component choice for smart conveyor sorting grids, small security gate prototypes, industrial counting loops, and autonomous warehouse rovers driven by Arduino, ESP32, or Raspberry Pi.
