Features of VL53LXX Laser-Ranging Module The VL53L1X sensor module is a laser-ranging sensor based on Time-of-Flight (ToF). The ToF method measures the distance to the object by measuring a wave’s total travel time (between the sensor and the object). With a maximum frequency of 50Hz, the VL53L1X sensor can measure distances up to a range of 4 meters.This low-power module is controlled through the I2C interface.In this module, unlike previous generations of distance measuring modules, IR and optic fil...
