VL53L1X Time of Flight Distance Sensor - ~40 to 4000mm

The VL53L1X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. The sensor contains a very tiny invisible IR source, and a matching detector. It measures how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Compare to Sharp IR distance sensors that try to measure the amount of light bounced, VL53L1X uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector. This approach ensures absolute distance measurements independent of ambient lighting conditions and target characteristics (e.g. color, shape, texture, and reflectivity), though these external conditions do affect the maximum range of the sensor, as do the sensor configuration settings.

The sensor includes voltage regulator for 3V to 5V supply and 3.3v / 5V logic level shifter.
