ESP32 Touch Pins. The ESP32 has 9 capacitive touch-sensing GPIOs. When a capacitive load (such as a human finger) is in close proximity to the GPIO, the ESP32 detects the change in capacitance. You can make a touch pad by attaching any conductive object to these pins, such as aluminum foil, conductive cloth, conductive paint, and so on. Because.


ESP32 touch sensor How to use touch pins as a button

The ESP32 chip comes with 48 pins with multiple functions. Not all pins are exposed in all ESP32 development boards, and some pins cannot be used. There are many questions on how to use the ESP32 GPIOs. What pins should you use? What pins should you avoid using in your projects?


ESP32 touch sensor How to use touch pins as a button

The esp32_touch component creates a global hub enabling (capacitive) touch detection on GPIO pins supported by ESP32, ESP32-S2 or ESP32-S3 processors. With this enabled, binary sensors may then be configured to permit touch detection. # Example configuration entry esp32_touch: setup_mode: false Configuration variables: ¶
