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.
FEATUREs
• Fully integrated miniature module
– Size: 4.9x2.5x1.56 mm
– Emitter: 940 nm invisible laser (Class1)
– SPAD (single photon avalanche diode)
receiving array with integrated lens
– Low-power microcontroller running advanced
digital firmware
• Pin-to-pin compatible with the VL53L0X
FlightSense ranging sensor
• Fast and accurate long distance ranging
– Up to 400 cm distance measurement
– Up to 50 Hz ranging frequency
• Typical full field-of-view (FoV): 27°
• Programmable region-of-interest (ROI) size on
the receiving array, allowing the sensor FoV to be
reduced
• Programmable ROI position on the receiving
array, providing multizone operation control from
the host
• Easy integration
– Single reflowable component
– Can be hidden behind many cover window
materials
– Software driver and code examples for
turnkey ranging
– Single power supply (2v8)
– I²C interface (up to 400 kHz)
– Shutdown and interrupt pins
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
