The sensor has 3 main components on its circuit board. First, the sensor unit at the front of the module which measures the area physically and sends an analog signal to the second unit, the amplifier. The amplifier amplifies the signal, according to the resistant value of the potentiometer, and sends the signal to the analog output of the module.The third component is a comparator which switches the digital out and the LED if the signal falls under a specific value. You can control the sensitivity by adjusting the potentiometer.
Please notice: The signal will be inverted; that means that if you measure a high value, it is shown as a low voltage value at the analog output.

Outputs a signal if the metal pike of the Sensor was touched. You can adjust the digital output threshold of the sensor.
Digital Out: At the moment of contact detection, a signal will be outputted.
Analog Out: Direct measuring value of the sensor unit.
LED1: Shows that the sensor is supplied with voltage
LED2: Shows that the sensor detects a magnetic field
