ST VL53L8CH User Manual

User manual
A guide for using the artificial intelligence enabler VL53L7CH and VL53L8CH
multizone Time-of-Flight (ToF) sensors
Introduction
The purpose of this user manual is to explain how to handle the VL53L7CH and VL53L8CH Time-of-Flight (ToF) sensors, using
the ultra light driver (ULD) API. It describes the main functions to program the device, the calibrations, and the output results.
The CNH data transform STMicroelectronics Time-of-Flight ranging sensor into a versatile optical sensor, which can enable
endless AI-based applications. This CNH raw data sent to the host, on top of the standard ranging data, opens the door to many
new applications beyond simple distance measurements. From solid material (carpet, wood, glass, mirror...) to gas or liquid
(water, oil, chemical...), it becomes possible to detect the location and the size of a cup in a coffee machine or beverage
dispenser, to sense the floor material for robotics, and develop advanced shape, motion, or hand posture recognition.
