Wide-range proximity sensing with immunity to sunlight
Proximity sensing with wide field-of-view (FoV) is getting more and more popular and important for people detection in many applications. This reference design from Texas Instruments uses optical time-of-flight (ToF) techniques to build small and cost-effective proximity sensor systems.
A single proximity and distance sensor AFE (OPT3101) with three external NIR LEDs, and one photodiode covers a total 120° wide FoV and outputs accurate distance of people activity.
