Grove Time of Flight Distance Sensor (VL53L0X)

PRODUCT DETAILS

Grove - Time of Flight Distance Sensor - VL53L0X is a high speed, high accuracy and long-range ToF distance sensor based on 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 whatever the target reflectances, unlike conventional technologies. It can measure absolute distances up to 2m, setting a new benchmark in ranging performance levels, 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 crosstalk.
