This module is a touch based detectionIC(TTP223B) of the capacitorSome dynamic typeTouch the switch module.This module is the default state output low level, models for low power consumption;When a finger touch the corresponding position, module, output level again touch back to low level.Mode switch for quick mode;When the last12Seconds without touch, mode and switch to a low power mode.Modules can be installed on the surface of non-metallic materials such as plastic, glass, in addition to the thin paper (non-metallic) covering on the surface of the module, as long as the accurate location of the touch, you can make it hidden in the place such as wall, desktop buttons.This module allows you to exempt from conventional type press buttons.
