VL53L1X
Long-distance ranging
time-of-flight (ToF) sensor
The VL53L1X is the third-generation laser-ranging sensor based on ST’s
patented FlightSense™ technology
This new generation VL53L1X
module includes a lens and
a low-power microcontroller
running advanced digital
firmware which ensures an
unprecedented absolute
distance measurement up
to 4 meters. It is also possible
to program the size and the
position of the Region of Interest
(ROI) on the receiving array to
reduce the sensor field-of-view
(FoV).
KEY BENEFITS
• Long range: up to 400 cm absolute dis-
tance measurement
• Fast: Up to 50 Hz ranging frequency
• High-accuracy ranging
• Low-power presence detection: <1.5mW
• Fully integrated miniature module:
4.9 x 2.5 x 1.56 mm
• Can be hidden behind cover glass
• Programmable sensor field-of-view (FoV)
TARGETED APPLICATIONS
• Advanced user detection for power-
saving and improved security in
personal computers and IoT devices
• Long distance and rapid obstacle
detection for robotics and smart
buildings
• Hovering and landing assistance for
drones
• Gesture recognition
• Camera and video assist (ultra-fast
autofocus)

TECHNOLOGY
The VL53L1X is a state-of-the-art long-distance ranging ToF sensor. It contains a sensing array of SPADs (single photon avalanche diode), an
integrated 940 nm invisible light source based on an eye-safe Class 1 VCSEL (vertical cavity surface-emitting laser) and a low-power embedded
microcontroller. This new generation sensor integrates a lens above the SPAD array, which enables measuring distances up to 4 meters, and
offers excellent ranging performance under challenging operating conditions, even when the sensor is hidden behind a colored cover window.
Unlike conventional IR sensors, the VL53L1X uses ST’s patented FlightSense™ technology which ensures absolute distance measurements
whatever the target color and reflectance.
Thanks to advanced on-board algorithms, it is also possible to reduce the sensor FoV by programming the size and the position of the region-of-
interest (ROI) on the receiving array.
An “Autonomous Low Power” mode is available, based on thresholding and interrupts, specially tuned for advanced Presence detection. It allows
significant system power-saving, switching-off or waking-up the host automatically when a human or an object is detected.
The VL53L1X is supplied with a complete documentation package, example source code and a software API (application programming interface)
which is compatible with a range of microcontrollers and processors. The application software development and the physical integration into
customers’ devices is easy thanks to the X-NUCLEO expansion board, breakout boards and associated development ecosystem.
MODULE DESIGN
The VL53L1X is “industrial design friendly”! It is a stand-alone, all-in-one ultra-small form factor module of 4.9 x 2.5 x 1.56 mm, which can be
hidden behind a wide variety of cover windows and reflowed on a motherboard or a flex PCB.
The VL53L1X is pin-to-pin compatible with the previous generation VL53L0X, which enables a natural evolution to this new generation.
