The 1-Channel Capacitive Touch Sensor Module uses the TTP223 Touch Sensitive IC to detect touch inputs, making it easy to add capacitive touch inputs to your project. Touch sensing ICs are designed to replace traditional direct selection with a variety of pad sizes. The module has one touchpad. After supplying 2 to 5.5V DC to the module, the touchpad is fully active and captures the input.
The single-channel capacitive touch sensor module is easy to connect. It can be used with or without a microcontroller or Arduino. If a capacitive load (such as a human hand) is in the immediate vicinity of the sensor pad, the sensor will detect the change in capacitance and activate the switch. Custom sensor pads can be made from almost any conductive material. These sensors can detect contact through thin layers of non-conductive materials such as glass, plastic, cloth and even wood.
Under normal conditions, the module output is low and the power consumption is low. Touching the corresponding position with your finger switches the module output to high, and if you do not touch it for 12 seconds, it switches to low power mode.
Jog Type: Low initial state, high touch, low non-touch (similar to touching a button)
module can be attached to surface plastic, glass, or non-metal material
thin As long as it is in the correct position for the (non-metallic) touch in addition to the paper, it can cover the surface of the module and hide it on walls, desktops, and other parts of the button.
