Metal Detector Sensor ModuleThis 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
