This is the metal touch sensor module. This sensor is an electronic switching device. Basically, it will operate when touched by a charged any part of the body it triggers a high frequency which is generated by the transistor that conducts an electrical pulse when to receive an electromagnetic signal. See below for the wiring guide.

Required Components.

  • Arduino UNO, MEGA, DUE, LEO, NANO, PRO, ESP8266 13, 12, 7, 11.
  • LED (Any Color)
  • Resistor 200 Ohms
  • Solder Less Bread Board
  • Jumper Wire
