The touch sensor is a digital input module, it’s a capacitive touch sensor. The touch sensor only has to be touched by an object to operate, it can be used as a touch switch.

We can’t figure out the logic high-level signal outputs by the touch sensor, but we can use output modules together with the touch sensor, such as a buzzer. As we know, the buzzer can be activated by a logic high-level signal, when we press the touch sensor, if the buzzer beep, then we can say the touch sensor outputs a logic high-level signal.


How does it work?

The main part of the touch sensor is a touch chip, the interface of the touch sensor is a digital interface, which means it has two output states, logic high-level and logic low-level.

1.When the touch sensor is touched by a capacitive object (such as your finger), it will output a logic high-level signal. Otherwise, it will output a logic low-level signal.
