KY-036 Metal Touch Sensor Module

The KY-036 Metal Touch Sensor Module is an analog and digital sensor that uses a transistor to detect changes in electrical conductivity. When the metal pin is touched with a finger, the conductivity changes and the module outputs both a digital and an analog signal. The digital output functions as a touch activated switch, while the analog output measures touch intensity. The detection threshold can be adjusted using the onboard potentiometer. This module is compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and similar microcontroller platforms.
