VL53L1X Distance Sensor
User Manual
OVERVIEW
VL53L1X Distance Sensor is a Time-of-Flight (ToF) ranging module based on the
VL53L1X from ST, with accurate ranging up to 4m and fast ranging frequency up to 50
Hz, it is controlled through I2C interface, and pretty low power consumption.
The VL53L1X is a ToF sensor which embeds the ST’s third generation FlightSense
patented technology. Compared with the second generation VL53L0X, the VL53L1X
extends the ToF ranging distance up to 4m, and features fast ranging frequency up to
50 Hz.
Unlike conventional ranging sensors, the VL53L1X integrates physical infrared
filters and optics, uses ST’s latest generation ToF technology which allows absolute
distance measurement whatever the target color and reflectance, achieves better
anti-interference capability.

HARDWARE
VL5 3L1X
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.
Features:
Fully integrated miniature module
– Size: 4.9x2.5x1.56 mm
– Emitter: 940 nm invisible laser (Class1)
– SPAD (single photon avalanche diode)
Version: V1.0.0 Date: 2018.06.25 3
