VL53l0x: Time-of-Flight Distance Sensor

Measure distance to an object by using a laser-based Time-of-Flight sensor. These sensors have a range of up to 2 meters and are pretty accurate.

You could use these for all sorts of things like measuring waterlevel in a container (without getting the sensor wet).

The sensor works by shining a laser onto an object, and timing how long it takes the light to be reflected back to the sensor.
