Reference Designs
Smart lighting & backlight control by ambient light & noise-immune proximity sensor reference design
Texas Instruments
This reference 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 environment ambient light levels. A capacitive proximity sensor saves power and increases 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 materialExcellent human-eye spectral response matching a strong IR rejection (Dynamically adjusts backlight brightness on a logarithmic scale based on how the human eye perceives brightnessIntegrated UV filter enables good performance for outdoor applications
