Metal 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 output signal indicating the presence of metal. These types of sensor can be used in a variety of applications, such as security systems, industrial automation, and even in hobby projects. The output can be digital or analog, some modules can even provide the depth of the metal. You can use this LC 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 sensor 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: “V+” ? Connect to power positive “V-” ? connect to power negative Adjust the potentiometer to vary the detection range and strength. Small and easy to use the module. It comes with a Buzzer for metal detection indication.
