Description:

The Touch Sensor Module is a digital input module, its 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 cant 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 logical high-level signal, when we press the touch sensor, if the buzzer beeps, then we can say the touch sensor outputs a logical high-level signal.

Specifications:

• Operating Voltage: 3.3V DC
• Supply mode: Crowbits Power Module

Features:

• Low power consumption
• Digital input module

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.

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.
