Technical overview

  • The VL53L1X measures distances using the time-of-flight method, which determines range by measuring returned light.
  • Maximum measurement accuracy is approximately ±10 % or better under optimal conditions.
  • It uses an infrared laser as the illumination source and a sensitive single-photon counting detector for ranging.
  • Multiple operating modes are supported, including Single Mode, Periodic Mode, and Waveform Histogram mode for different applications.
  • Power supply is typically 3.3 V; exact voltage requirements should be derived from the datasheet.
  • Communication uses the I2C interface with default address 0x52; the address can be modified when multiple sensors are operated in parallel.
  • The product is categorized under “Modules, Sensors, Light”.
  • Available resources include a user manual, schematics, demo code, and software libraries (e.g., Arduino library).
  • A Python demo is available for quick start-up.
  • The device is classified in the “TOF Laser Range Sensor” category.

Commands and examples – verify before use:  

Default I2C address: 0x52
Modify I2C address: see SparkFun_VL53L1X_Arduino_Library issue #7

Notes and version constraints

  • Exact voltage values and power consumption are not fully specified in the source text – please consult the datasheet.
  • The “range up to 4 m” statement comes from the product name; detailed accuracy claims are context-dependent and must be validated according to environment conditions.
  • Operating multiple sensors on one bus requires individual address changes; the exact steps depend on the library used.
  • Python sample code references external links; local availability needs confirmation.
  • Technical support is provided during business hours Mon–Fri, 9 AM–6 PM GMT+8.
