Mini Metal Detector Module

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.

Features:

• Operating voltage: 5V DC.
• Detector distance: 1CM.
• “V+” ↔ Connect to power positive.
• “V-” ↔ connect to power negative.
• Adjust the potentiometer, let the modules work normally.
• Small and easy-to-use module.
• It comes with a Buzzer for metal detection indication.
