MJKDZ Touch Switch Module

Description
Touch Switch Module (Key Touchpad) package contains of single touchpad switch which are based on a single key touchpad detector chip. This chip presents one touchpad switch to appreciate replacing of single tactile button switch and traditional direct key. This chip is very sensitive to the total loading of electrode size and connecting line capacitance on the module PCB, so the sensitivity of touchpad is depended on the design specification. In this module, touchpad and line are accurately tuned to make an appretiate touch pad switch. This touch module has a good sense of human skin and body to stable detect any touching.
This module can be supplied with a wide range of voltage, but with very low power consumption. Therefore this module can widely be applied in DC and AC devices and Arduino projects, replacing button key or switch. This module has a mono-color LED indicator to show touching which is may be red, green, or blue.
