Adafruit VL53L4CD Time of Flight Distance Sensor, 1-1300 mm
Adafruit VL53L4CD Time of Flight Distance Sensor, 1-1300 mm
The Adafruit VL53L4CD Time of Flight Sensor is another great time of ST's flight distance sensor in the VL5 series of chips, this is ideal for shorter distances. The sensor contains a very tiny invisible laser source and a matching sensor. The VL53L4CD can detect the "flight time", or how long the light lasts for the sensor to bounce. As it uses a very narrow light source, it is good for determining the distance 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 has no linearity problems or "duplication" where you can't see if an object is very far or very close.
