Description

This Touch Sensor is Capacitive Touch based on touch detection IC (TTP223B). It is Arduino Compatible and has the low power consumption power mode. When it is touched by a finger, the module will output high power and is switched to fast mode. If the sensor is not being used for 12 seconds, it switches to low power mode. The module can be installed in enclosures such as plastic, glass surface and non-metallic materials (in addition to a thin piece of paper (non-metallic) covering the surface of the module, as long as the touch of the correct position). You can even hide it in a wall of a building, desk and other places instead of using a visible button.
