The VL53L1X sensor is a long-range proximity and ranging sensing that base on TOF (Time-of-Flight) unlike IR (Infrared) sensor which measure only signal strength and can be affected by the object reflectivity, compare to VL53L1X its measures directly to a distance base on the time for emitted photons to be reflected, enabling an accurate distance ranging regardless of the object surface characteristics. This device is package in All-in-one miniature module which contains the laser driver and emitter as well as the single photon avalanche diode or (SPAD) light receiver that gives the sensor their ranging speed and reliability at low power consumption.
The VL531X can be used as host of application such proximity sensing, camera autofocus and video assist, vacuum cleaner, robotics, cliff detection, collision and avoidance, drones for hovering and landing assistance, home application such as ambient light sensing, gesture recognition for light management, automatic doors control, power saving for auto awake and auto sleep, personal computing devices, IOT, toilet, faucets, soap dispensers, package counter, aid inventory management or DIY smart furniture’s. etc. for further reading and technical details please refer to the datasheet below or watch the video for introduction of FlightSense proximity sensor.
