חיישן מתכת ארדואינו KY-036

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.

Compatible with popular microcontroller boards like Arduino, ESP32, ESP8266 and Raspberry.
