The VL53L0X TOF (Time-of-Flight) Laser Distance Sensor is a compact and highly accurate distance measurement module that uses laser-based TOF technology to measure distance by calculating the time taken for light to reflect back from an object. Unlike ultrasonic sensors, it provides fast, precise, and stable readings even for small objects, making it perfect for robotics, automation, obstacle detection, and proximity sensing projects. It communicates using the I2C interface, so it is easy to connect with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
