Laser Range Finder Technical Instruction LRF G905 59

1. Summarize The ranging module is high integration, low power consumption and light weight. It could provide distance measurements quickly and accurately for the main control system; The range accuracy is ±1m. It has the TTL interface (could communicate with MCU directly) or by RS 232 serial port through adapter. It facilitate customer’s redevelopment work and build their own ranging system. 2.

1: Laser emission aperture 2: Laser receiving aperture 4: Positive electrode of battery (CR 2-3V) 5: Negative electrode of battery (CR2-3V) 3.1 Factors that influence ranging capability 1) Target reflectivity: Generally speaking, the higher the reflectivity of the object, the better the ranging ability. for example, for moderate reflectivity object, the measuring range is 600M, and it can up to 800M for high reflectivity object, but may be only 300M for low reflectivity one. The ranging ability of other objects can be got the same conclusion. ( It may be fail to measure the target that can hardly...

4) Environment factor: the environment factors including sunshine intensity, the concentration of water vapor in the air and suspended particles, deviation from the Angle of sunlight, etc. (such as rain, fog, snow, fog, haze, etc.) 3.2 Suitable measurement target The product is suitable for measuring high reflectivity objects (such as highway’s signpad), moderate reflectivity objects (such as building’s wall) and low reflectivity objects (such as tree, golf flag, utility pole, animal etc.) When the reflectance is reduced to a certain extent, the range will be reduced accordingly. Building’s Wall...
