The TF-Luna Lidar Ranging Sensor is a compact and efficient laser ranging module designed for a variety of applications that require accurate distance measurement. It operates on Time-of-Flight (TOF) ranging principle, which means it calculates the distance by measuring the time taken for the laser light to travel to the target and back. The sensor can accurately measure distances up to 8 meters and is designed to be energy-efficient, making it ideal for battery-powered devices.

With its compact size for easy integration, UART And I2C interfaces support for use with controller boards like Raspberry Pi/Raspberry Pi Pico/ESP32/Arduino, and a mini laser module to emit the laser pulses, ensuring precise and focused measurements, this sensor is a powerful and versatile device suitable for distance measurement, obstacle detection, and navigation in numerous applications across industries. Its combination of long-range capability, low power consumption, and compact design makes it an attractive choice for developers and engineers seeking reliable-ranging solutions!
