Description

The TIDA-00754 TI Design demonstrates a proximity sensor implementation for HMI applications. The design can be used for backlight control that dynamically adjusts LCD backlight brightness relative to the environment's ambient light levels. A capacitive proximity sensor saves power and increases the LCD backlight life by waking up the system from sleep or standby mode when a person approaches.

Features
  • Demonstrates EMI-resistant proximity detection using copper PCB material
  • Excellent human eye spectral response matching with a strong IR rejection (<1%)
  • Dynamically adjusts backlight brightness on a logarithmic scale based on how the human eye perceives brightness
  • Integrated UV filter enables good performance for outdoor applications
