The Adafruit VL53L4CD Time of Flight Sensor is another great Time of Flight distance sensor from ST in the VL5 series of chips, this one is great for shorter distances. The sensor contains a very tiny invisible laser source and a matching sensor. The VL53L4CD can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL53 is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.
