The VL53L1X time-of-flight sensor from STMicroelectronics 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.

Unlike other proximity sensors that use simple IR (Infra-Red) technology, which only measure signal strength and can be affected by the object’s reflectivity, FlightSense sensors directly measure 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.
