FlightSense time-of-flight sensor with 4-meter range and auto power-saving

By eeNews Europe



FlightSense sensors work by measuring the time it takes for photons to be reflected from the measured object, rather then using simple IR technology. This method provides higher accuracy, which doesn’t depend on the surface characteristics of the object.

The VL53L1X combines low power consumption with fast measurements, making it ideal for applications such as mobile robotics and collision detection for UAVs. The device has a power-saving presence-detection mode that allows auto-sleep/wake-on-approach use cases. The VL53L1X comes in a 4.9mm x 2.5mm x 1.56mm package and is pin-compatible with its VL53L0X predecessor for easy upgrading. The package contains the laser driver and emitter, as well as the Single-Photon Avalanche Diode (SPAD) light receiver. VL53L1X opertaes on the non-visible spectrum at 940nm, eliminating light emissions and allowing the device to be hidden behind a protective window without impairing performance.
