VL53L1 New generation Time-of-Flight ranging sensor with advanced multi-zone and multi-object detection Datasheet - production data Applications Laser assisted auto-focus (AF): enhances the camera AF system speed and robustness, especially in difficult scenes (low light and low contrast) ideal companion for PDAF sensors Video focus tracking assistance at 60 Hz Scene understanding with multi object detection: choose the focus point Dual camera stereoscopy and 3D depth assistance thanks to multi zone measurement Features Presence detection (autonomous timed mode), Fully integrated miniature module typically to lock/unlock and power on/off Emitter: 940 nm invisible laser (VCSEL) devices like notebooks, tablets or white goods and its analog driver Receiving array with integrated lens Description Low-power microcontroller running The VL53L1 is a state-of-the-art, Time-of-Flight advanced digital firmware (ToF), laser-ranging, miniature sensor enhancing Size: 4.9 x 2.5 x 1.56 mm STMicroelectronics FlightSense product family. Fast, accurate distance ranging Housed in a miniature and reflowable package, it 400 cm+ detection with full field of view integrates a SPAD (single photon avalanche (FoV) diode) array, physical infrared filters and optics to achieve the best ranging performance in various 60 Hz ranging capable up to 300 cm ambient lighting conditions, with a wide range of Immune to coverglass cross-talk and cover windows. fingerprint smudge at long distance with patented algorithms (direct ToF) Unlike conventional IR sensors, the VL53L1 uses Multi-object detection capability STs latest generation direct ToF technology which allows absolute distance measurement Multi-zone scanning with selectable array whatever the target color and reflectance. It (2x2, 3x3, 4x4, or defined by user through provides accurate ranging above 4 m and can software) work at fast speeds (60 Hz), which makes it the Easy integration fastest miniature ToF sensor on the market. Reflowable component With patented algorithms and ingenious module Single power supply 2v8 construction, the VL53L1 is also able to detect Works with many types of cover glass different objects within the field-of-view with materials depth understanding at 60 Hz. IC interface (up to 1 MHz) Scene browsing and multi-zone detection is Xshutdown (reset) and interrupt GPIO now possible with the VL53L1, thanks to software Full set of software driver (Linux and customizable detection array for quicker touch- Android compatible) for turnkey ranging to-focus or mini depth-map use cases.
