Metal Detector Sensor Module TEC1 12715 There are other two buttonsMetal Detector Sensor Module A metal detector sensor module is a device that uses electromagnetic induction to detect the presence of metal objects. The module typically consists of a transmitter coil that generates a magnetic field, and a receiver coil that detects changes in the magnetic field caused by the presence of metal. When a metal object comes into proximity of the sensor, it will disrupt the magnetic field and the sensor will generate an
