The VL53L1X is a stateoftheart TimeofFlight (ToF) laserranging sensor based on ST's FlightSense technology, capable of measuring distances up to 4 meters with a fast 50Hz update rate . Unlike traditional IR sensors, its absolute distance measurement is unaffected by the target's color or reflectance .
| Parameter | Value |
|---|---|
| -- | -- |
| Ranging Distance | 40mm to 4000mm (4 meters) |
| Ranging Frequency | Up to 50Hz |
| Field of View (FoV) | 27° typical |
| Laser Wavelength | 940nm (invisible Class 1 laser) |
| Ranging Accuracy | ±5% |
| Interface | I2C (supports level shifting) |
| Operating Temp | -20°C to 80°C |
The sensor integrates a SPAD receiving array, a 940nm invisible Class 1 laser emitter, and physical infrared filters in a single module . It supports programmable ROI (Region of Interest) to reduce the Field of View when needed .
√ Compatible with Arduino (Adafruit and SparkFun libraries), STM32, and Raspberry Pi
√ Includes shutdown (SHUT) and interrupt (INT) pins for lowpower and eventdriven control
