Abstract

A miniature portable laser ranging system based on an STM32 microcontroller and VL53L0X time-of-flight laser ranging sensor was developed. An LCD display indicates the real time measured range value. Two working modes with different accuracy and detectable range were designed. These comprise high accuracy and long-distance modes which make the equipment very versatile for real applications. Following code optimization and verification by calipers, the relative measurement error is around 1% – 2% for both modes.
