Grove - Time of Flight Distance Sensor(VL53L0X)

DESCRIPTION

The Grove - Time of Flight Distance Sensor is a high speed, high accuracy and long range distance sensor based on the VL53L0X.

The VL53L0X is a new generation Time-of-Flight (ToF) laser-ranging module housed in the smallest package on the market today, providing accurate distance measurement of whatever reflects off the target. Unlike conventional technologies, it can measure absolute distances up to 2m, setting a new benchmark in ranging performance levels, and opening the door to various new applications.

The VL53L0X integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST’s second generation Flight SenseTM patented technology.

The VL53L0X’s 940 nm VCSEL emitter (Vertical Cavity Surface-Emitting Laser), is totally invisible to the human eye, coupled with internal physical infrared filters, it enables longer ranging distances, higher immunity to ambient light, and better robustness to cover glass optical cross-talk.
