Applications

? User detection (autonomous low-power mode) to

power on/off and lock/unlock devices like

personal computers/laptops and the IoT

? Service robots and vacuum cleaners (long

distance and fast obstacle detection)

? Drones (landing assistance, hovering, ceiling

detection)

? Smart shelves and vending machines (goods

inventory monitoring)

? Sanitary (robust user detection whatever the

target reflectance)

? Smart building and smart lighting (people

detection, gesture control)

? 1 D gesture recognition

? Laser assisted autofocus which enhances the

camera autofocus system speed and robustness,

especially in difficult scenes (low light and low

contrast) and video focus tracking assistance

Description

The VL53L1X is a state-of-the-art, Time-of-Flight (ToF), laser-ranging sensor, enhancing the ST FlightSense product family. It is the fastest miniature ToF sensor on the market with accurate ranging up to 4 m and fast ranging frequency up to 50 Hz

Housed in a miniature and reflowable package, it integrates a SPAD receiving array, a 940 nm invisible Class1 laser emitter, physical infrared filters, and optics to achieve the best ranging performance in various ambient lighting conditions with a range of cover window options.

Unlike conventional IR sensors, the VL53L1X uses ST’s latest generation ToF technology which allows absolute distance measurement whatever the target color and reflectance.

It is also possible to program the size of the ROI on the receiving array, allowing the sensor FoV to be reduced.
