Metal Detection Module
You can use this LC Metal Detector Non-Contact Metal Induction Detection Module as a metal detector. When it approaches a metal, it makes a noise.
This is a module specially designed to detect metal. The module works by inducing currents in metal objects and reacting when they occur. A nice built-in buzzer indicates when it detects something and a built-in potentiometer allows adjustment of the sensitivity.
The power cables from the metal detector's non-contact metal induction detection module must be soldered for the module to function, positive on the outside of the module and negative between the potentiometer and an electrolytic capacitor.
Characteristics :
1. "V +" ↔ Connect to positive current
2. Connect “V-” ↔ to negative power
3. Adjust the potentiometer, let the modules work normally.
4. Small and easy to use module.
5. It comes with a buzzer for metal detection indication
