About this item
TTP223 Capacitive Touch Sensor Red TTP223 Capacitive Touch Sensor Module – Red is based on a touch-sensing IC (TTP223) capacitive touch switch module. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. In the normal state, the module output low, low power consumption. When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode. The TTP223 is a touch pad detector IC replicating a single tactile button. This touch detection IC is designed for replacing traditional direct button key with diverse pad size. This versatile small sensor board is user configurable with on-board shorting pads as activated Low or High, momentary or latching output to suit for various control requirements. This touching detection module is designed for replacing traditional mechanical button switch with diverse pad size with no wear and tear problem of mechanical switches. Jog type : the initial state is low , high touch , do not touch is low ( similar touch of a button feature ). Module can be installed in such as surface plastic, glass of non-metallic materials 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.
