New Multi-Zone Time-of-Flight Ranging Sensor with Wide Field of View
Introducing a new state-of-the-art laser-ranging sensor with multi-zone detection and wide field of view
This webinar was broadcast on Thursday, July 8th, 2021
Join ST for 1 hour during this on-demand webinar to discover the latest advance in accurate, multi-zone laser-ranging sensors from the FlightSense™ family.
In this session we unveil the VL53L5CX, a new Time-of-Flight (ToF) ranging sensor that exploits an integrated SPAD (single photon avalanche diode) array, physical infrared filters, and diffractive optics to achieve optimal ranging performance over a wide range of ambient lighting conditions and cover glass materials. We will show you how the device's multi-zone reading and wider field of view (FoV) enable exciting new opportunities for applications like presence-based thermostat control, gesture recognition, liquid level sensing, and much more.
Unlike conventional infrared sensors, the VL53L5CX uses direct ToF technology for absolute distance measurement regardless of the target color and surface reflectance. It provides accurate high-speed ranging up to 13 ft (400 cm), making it the fastest multi-zone miniature ToF sensor on the market.
You will understand how ST's patented histogram algorithms make it possible to detect multiple objects within the sensor's FoV and provide cover-glass crosstalk immunity beyond 23 in (60 cm). In addition, multi-zone distance measurement can be achieved up to 8x8 zones with a wide 63° diagonal FoV, which can be reduced by software.
You will learn:
- The benefits of multi-zone detection vs single-zone
- The multiple applications enabled by the VL53L5CX, including gesture recognition, hand tracking, and liquid level sensing
- How the device can detect human presence
- How to use the evaluation kit to prototype and test your design
