Metal Detection Module Contactless Metal Induction

<p>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.</p> <p><strong>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.</strong></p> <p>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.</p> <hr /> <h4><strong>Features :</strong></h4> <ol> <li>“V+” ↔ Connect to power positive</li> <li>“V-” ↔ connect to power negative</li> <li>Adjust the potentiometer, let the modules work normally.</li> <li>Small and easy to use module.</li> <li>It comes with a Buzzer for metal detection indication.</li> </ol> <hr /> <h4><strong>Package Includes :</strong></h4> <p>1 x Metal detector non contact metal induction detection module.</p>
