Bringing high-accuracy, low-power distance measurement and proximity detection to an even wider variety of applications, ST has launched what it believes is the fastest miniature Time-of-Flight (ToF) laser-ranging sensor. The VL53L1X sports accurate ranging up to 4 m and fast ranging frequency up to 50 Hz.

The sensor is said to enable accurate distance-ranging regardless of the object’s surface characteristics. It also sports low power consumption and fast ranging performance.

Applications of the VL53L1X  include 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 miniature sensor, based on ST’s FlightSense technology, measures only 4.9mm x 2.5mm x 1.56mm. 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 for unrivaled ranging speed and reliability.

The VL53L1X is in production now
