STMicroelectronics introduces the VL53L1X time-of-flight sensor which extends the detection range of ST’s FlightSense technology to four meters, bringing high-accuracy, low-power distance measurement, and proximity detection to an even wider variety of applications.
While the other proximity sensors use simple IR (Infra-Red) technology, which only measure signal strength and can affect the object’s reflectivity, FlightSense sensors from STMicroelectronics directly measure the distance to the object based on the time for emitted photons to be reflected, enabling accurate distance-ranging regardless of the object’s surface characteristics.
With low power consumption and fast ranging performance, STMicroelectronics’ VL53L1X is ideal for mobile robotics for wall following, cliff detection, collision avoidance and hover/landing assistance for drones or unmanned aerial vehicles (UAVs). The power-saving presence-detection mode enables innovative auto-sleep/wake-on-approach use cases for PCs, notebooks and IoT devices, in addition to camera auto-focus assist, and gesture recognition.
Further applications include washroom automation in toilets, faucets or soap dispensers, and package counting to aid inventory management in vending machines or smart-shelf systems.
The Key Feature of the VL53L1X Flight Sensors includes:
- The fully integrated and miniaturized VL53L1X measures only 4.9mm x 2.5mm x 1.56mm, maing it compatible to use even where the space is very limited.
- It is also pin-compatible with its predecessor, the VL53L0X, allowing easy upgrading of existing products.
- The compact package contains the laser driver and emitter as well as the Single-Photon Avalanche Diode (SPAD) light receiver that gives ST’s FlightSense sensors their unrivaled ranging speed and reliability.
- Furthermore, the 940nm emitter, operating in the non-visible spectrum, eliminates distracting light emission and can be hidden behind a protective window without impairing measurement performance.
STMicroelectronics’ FlightSense technology is already being used in a range of products marketed successfully worldwide.
The VL53L1X from ST will soon be made available in the market.
