Description

ADIY TTP223 Touch Sensor Red Module – TTP223 Capacitive Touch Switch is made in India and it is based on a touch-sensing IC (TTP223). It allows you to remove the worry of conventional push-type keys. Normally, it outputs low and keeps at 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 low power state again.

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. In addition to the thin paper (non-metallic) covering the surface of the module, as long as the correct location of the touch, you can make hidden in the walls, desktops, and other parts of buttons.

Jog type: the initial state is low, high touch, do not touch is low (similar touch of a button feature)
