Description
The TTP224 4-way Capacitive Touch Switch Module is a touch sensor based on the TTP224 touch sensing IC. This sensor module has 4 touchpads, where it touches with the finger, it gives the signal from the output pin. This module performs four sensor functions simultaneously. There are also four output pins for four touchpads. When the touchpad is touched, a signal is sent out on its output pin. By connecting these signal pins to the microcontroller, we can make a project based on the touch switch.
