Overview
Description
A touchless button solution can be widely used in homes (lighting switches, bathroom switches, etc.) and public locations (vending machines, electric door openers, etc.). A touch can be detected without directly touching the button; therefore, the adhesion of bacteria and dirt to the fingers is reduced. The touchless button solution lessens concerns over contaminated surfaces.
Renesas offers a reference design for the touchless button solution. To learn more, see the Touchless Button Reference Design page.
System Benefits:
- Entry-level RA 32-bit MCU with a Capacitive Touch Sensor Unit 2 (CTSU2) provides touchless control with high sensitivity and high noise immunity. All Renesas MCUs that contain a CTSU are also compatible.
- Ultra-low Iq buck-boost can fully extract the power of a battery as low as 1.8V.
- Output voltage can be adjusted by the I2C bus.

Touchless Button Reference Design
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...
