This solution performs low power consumption standby by using the automatic judgment function of CTSU2SL and the multi-electrode connection function.  

We prepared a demonstration of self-capacitance waterproof button. The solution can compare the Waterproof of GND shields and Active shields for self-capacitance button.

The touchless button reference design applies Renesas capacitive solutions to detect approaching fingers and hands without physical contact. Two types of reference design, Demo solution and electrode boards are available.

The 3D gesture demo applies Renesas' capacitive touch solution to realize an HMI that detects gesture motions (up and down, left and right, and forward and back) of a hand in a three-dimensional space. A standard version (160mm sq.) and small version (80mm sq.) are available.

As a capacitive sensor application, we prepared a demonstration of water level measurement using the Renesas capacitive touch solution.
