Arduino KY-036 Metal touch sensor module

Module has a power led and a led indicating touch of metal.
A0 seems to contain some analog out signal also to indicate if metal is touched.
Module contains a variable resistor (sensitivity?)


  • D0          Arduino Pin 3
  • +            +5V
  • GND       GND
  • A0          (not connected / Analog signal) 


If metal wire over the transistor is touched Arduino led (pin13) is switched on
