Touch keypad function by measuring the capacitance of 16 electrode points.
This compact inexpensive keypad, can connect to any Capacitive module. In our catalog you can find 16-Key Capacitive touch module which is based on TTP229 and connects to microcontroler via I2C bus.
This touch keypad, is both an ideal learning tool for capacitive touch sensing keypads, as well as a fully operational touch keypad that can be easily incorporated in a professional control system or microcontroller application.
Touch pads have numbers from 1 to 16, and can be marked with felt-pan.
