Metal detector non-contact metal induction detection module

DescriptionYou 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 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 negativeAdjust the potentiometer, let the modules work normally.Small and easy to use module.It comes with a Buzzer for metal detection indication.Package Includes :1 x Metal detector non contact metal induction detection module.
