TTP226 Digital Touch Sensor Switch Module 8 Channel Self-Locking No-Locking Capacitive Button
Capacitive type touch jog switch module The module is based on a touch detection IC (TTP226). Under normal conditions, the module output low, low-power mode to mode; a touch of a finger when the corresponding position, the module will output high, the mode is switched to fast mode; when for 12 seconds without touching, the mode and switch to low power mode. The module can be installed in such as plastic, glass surface 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, and other parts of the desktop button. This module allows you to remove the troubles of conventional push-type buttons.
