This sensor is used to detect touches. It emits a signal if the front metal tip of the sensor is touched. The sensitivity of the sensor can be adjusted by means of a controller. It is ideally suited for threshold measurement. This means that the sensor emits a digital high signal as soon as a threshold value set by the user is exceeded. However, this also means that the analog measured values are not suitable for conversions, as the analog signal is also influenced by the rotary potentiometer.
The KY-036 sensor module has a power LED, a touch detection LED, touch sensor plate, and 4 pins. The pins are as follows:-
1. GND
2. VCC
3. AO (analog output)
4. DO (digital output)
