Laser Rangefinder Module

LRF Series eye-safe ranging module is developed based on 1535nm erbium-glass laser independently developed by our company. It belongs to levelⅠeye-safe product. The product adopts monopulse ranging, the maximum range is up to 20km. Support UART(TTL_3.3V), RS232 and RS422 (Full duplex) electrical interface (One out of three), provide upper computer software, Specifies the set and communication protocol. The advantages are stable operation functions, small size and light weight.
