Sales Briefcase
  • The VL53L1 API is a set of C functions controlling the VL53L1 device (e.g. init and ranging) to enable the development of end-user applications. The API is structured in a way that it can be compiled on any kind of platform through a well isolated platform layer (mainly for low-level I2C access). One example code is provided to show how to use the API and perform ranging measurements.

    The VL53L1 is a state-of-the-art, Time-of-Flight (ToF), laser-ranging, miniature sensor enhancing STMicroelectronics’ FlightSense product family. Housed in a miniature and reflowable package, it integrates a SPAD (single photon avalanche diode) array, physical infrared filters and optics to achieve the best ranging performance in various ambient lighting conditions, with a wide range of cover windows.
    Unlike conventional IR sensors, the VL53L1 uses ST’s latest generation direct ToF technology which allows absolute distance measurement whatever the target color and reflectance. It provides accurate ranging above 8 m and can work at fast speeds (60 Hz), which makes it the fastest miniature ToF sensor on the market.
    With patented algorithms and ingenious module construction, the VL53L1 is also able to detect different objects within a field-of-view with depth understanding at 60 Hz.
    Scene browsing and multi-zone detection is now possible with the VL53L1, thanks to software customizable detection array for quicker “touch-to-focus” or mini depth-map use cases.
