Overview
Description
The touchless button reference design can detect the approach of fingers and hands without physical contact using Renesas’ capacitive touch solution. The electrode detects the proximity of the finger via self-capacitance and turns on the LED. The demo solution is compatible with all types of Renesas capacitive touch CPU boards.

Features
- Based on Renesas' high sensitivity, noise-tolerant capacitive touch solution
- Detect the approach of a finger up to 15mm above the electrode
- Sensing can be carried out with any non-conducting material like glass or paper
- Support for IEC 61000 4-3 Level 3 Class B*
- Applicable to various applications such as white goods and public facility
- Realize system control and touchless operation for your product using a high-performance, low power 32-bit microcontroller (MCU) and touch IP
- Possible to use touchless control combined with other capacitive applications (water level measurement + touchless button)
*Class B: No false detection when there is no object nearby in a noisy environment.
