Metal Touch Sensor KY-036 | Explanation and Interfacing with Arduino | Practical Demonstration

The KY-036 Metal Touch Sensor Module is an analog/digital sensor that uses a transistor to detect changes in electrical conductivity. When the transistor is touched with a finger, the conductivity changes and the module emits a digital and analog signal.
The digital output can be used a switch that changes state when touched. The analog output can measure the intensity of the touch. The detection threshold can be regulated using the on-board potentiometer.
This module consists of a transistor to detect touch, an LM393 differential comparator to control the digital output, a 3296W potentiometer to adjust the detection threshold, 6 current limiting resistors, 2 indicator LEDs and 4 male header pins. The module features analog and digital outputs.
