What Is a Laser Rangefinder Module?

A laser rangefinder module is a compact electronic component designed to measure distances using laser technology. The module emits a laser beam towards a target and calculates the time it takes for the beam to reflect back, a method known as time-of-flight (ToF). This enables precise and reliable distance measurements in various environments and conditions.

These modules are commonly integrated into devices like handheld laser rangefinders, autonomous robots, drones, and industrial equipment, making them indispensable in modern technology.
