Laser rangefinder module 1200m typically works by emitting a laser pulse and measuring the time it takes for the pulse to bounce back after hitting an object.
UART interface allows the 905nm laser rangefinder module to communicate with the drone's control system or other devices using serial communication.
The maximum distance at which the uart laser rangefinder module sensor can accurately measure 1200m. Note that the effective range might be less depending on factors like reflectivity of the target surface, atmospheric conditions, etc.
This laser range finder module serial is integrated to device by TTL designed specifically for use on a drone pod. It ensures the laser distance sensor 905nm is properly positioned and measured while in flight.
