STMicroelectronics, VL53L1, Time-of-Flight Ranging Sensor

 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.
