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 [citation:2][citation:5]. Unlike traditional IR sensors, its absolute distance measurement is unaffected by the target's color or reflectance [citation:1][citation:5].
| Parameter | Value |
|---|---|
| :- | :- |
| Ranging Distance | 40mm to 4000mm (4 meters) [citation:1][citation:5] |
| Ranging Frequency | Up to 50Hz [citation:2][citation:5] |
| Field of View (FoV) | 27° typical [citation:1][citation:5] |
| Laser Wavelength | 940nm (invisible Class 1 laser) [citation:1][citation:5] |
| Ranging Accuracy | ±5% [citation:1][citation:5] |
| Interface | I2C (supports level shifting) [citation:1][citation:5] |
| Operating Temp | -20°C to 80°C [citation:1][citation:5] |
The sensor integrates a SPAD receiving array, a 940nm invisible Class 1 laser emitter, and physical infrared filters in a single module [citation:2]. It supports programmable ROI (Region of Interest) to reduce the Field of View when needed [citation:3].
√ Compatible with Arduino (Adafruit and SparkFun libraries), STM32, and Raspberry Pi [citation:4][citation:8]
√ Includes shutdown (SHUT) and interrupt (INT) pins for lowpower and eventdriven control [citation:1]
