Description

The Digital Sensor TTP223B Module Capacitive Touch Switch is based on a touch-sensing IC (TTP223B) capacitive touch switch module. Allows you to remove the worry of conventional push-type keys. It is based on a capacitive touch switch module IC (TTP223B). If the module is mounted on surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks.

Digital Capacitive Touch Switch Module is based on TTP223B. Normally, it outputs low and keeps at a low power state. When a touch is sensed on the circular marked region, it outputs high and switches to the quick response state. When not being touched for 12 seconds, it switches to a low power state again.

In addition to the thin paper ( non-metallic ) covering the surface of the Digital Sensor TTP223B Module, as long as the correct location of the touch, you can make hidden in the walls, desktops, and other parts of buttons. Its positive and negative can be used as a touch surface, it can replace the traditional touch button.
