Reference Designs
Wide-range (120° FoV at 1.6 meters) proximity sensing reference design with immunity to sunlight
Texas Instruments
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 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.
Features
- 3 NIR emitters support up to 3 zones of detection with a single OPT3101Total system field-of-view (FoV) of 120 ° is covered by three LED emitters and one photodiodeDetection range up to 1.5 meters without lensAdaptive HDR allows measurement insensitive to object color and reflectivity and supports operation under high ambient condition (outdoor and indoor conditions)Proximity sensing and direct distance measurement output with accuracy of ±10% Exempt group lamp classification LED as emitter
