Metal Detector Sensor Module

This is a Metal detector sensor module that utilizes a floating lead of Darlington transistor to detect the touch. There are two LEDs available on the PCB where one is for power indication and the other one illuminates when touch is detected.

Features:

• Main chip: LM393
• Working voltage: for DC 5V
• Single-channel signal output
• Low-level output signal used for human body touch sensor alarm
• Adjustable sensitivity
• Pin Connector to board: 4 Pins
• Its make in India
