Laser distance sensors are becoming increasingly popular in robotics, industrial automation, smart devices, and research projects. Compared with ultrasonic sensors or infrared sensors, laser sensors generally provide higher accuracy, longer measuring distances, and faster response times.

In this article, I'll demonstrate a simple way to connect a Raspberry Pi to a UART laser distance sensor and continuously read distance measurements using Python.

The approach works for many serial laser distance sensors that support TTL UART communication.
