description 1 3 Pinout 2 4 Functionality of the sensor 2 5 Code example Arduino 3 6 Code example Raspberry Pi 4 Picture Technical data / Short description Outputs a signal if the metal pike of the Sensor was touched. You can adjust the sensitivity of the sensor with the controller. 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 Export: 16.06.2017 Copyright by Joy-IT - Published under CC BY-NC-SA 3.0 Page 159 of 214 KY-036 Metal-touch sensor module Pinout Functionality of the sensor The sensor has 3 main ponents 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 ponent is a parator 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...
