VL53L0X The world's smallest ToF distance sensor

VL53L0X is a second-generation laser ranging sensor based on STMicroelectronics' proprietary FlightSense technology

The VL53L0X is the smallest ToF sensor on the market today that fully integrates and embeds a human-safety laser sensor, advanced filter and ultrafast photon detection array.

The ability to measure longer distances with fast, accurate and reliable solutions opens the door to new applications and further complements the ST FlightSense product family.

The main advantage:

The absolute distance reading of up to 2 meters is available in less than 30ms (in mm)
Fast mode: 50 Hz fast ranging operation
High precision
Low power consumption
4.4 × 2.4 × 1 mm reflow package
Advanced ambient light suppression design
Using 940nm invisible light
Requirements Optical cover support

Target Applications:

Camera Assist (Ultra-Fast AF and Depth of Field)
Energy-saving test on smart phone or laptop
Gesture control
UAV
Robot and industrial control
IoT
Household appliances

technology

The VL53L0X incorporates an integrated 940nm light source based on a SPAD (Single Photon Avalanche Diode) sensor display and a body-confined VCSEL (Vertical Cavity Surface Emitting Laser) for use with algorithms running on embedded microcontrollers Directly determine the distance in millimeters of the target object, even under challenging operating conditions and independent of the target reflectivity. The VL53L0X features an ultra-low power system architecture ideal for wireless and IoT applications. The VL53L0X has a complete documentation package such as source code and software APIs (application programming interfaces) that are compatible with GF's microcontrollers and processors.

Module design

With its small 4.4 × 2.4 × 1 mm size and reflow solderability, the VL53L0X is easy to integrate with the main PCB or flex board of the product and can be hidden under a variety of cover material. At present, the VL53L0X is the only product that integrates a VCSEL with a wavelength of 940nm, which is invisible and not susceptible to background lighting.
