A high precision visibility meter based on forward scattering is designed by using photoelectric sensor.The receiver of visibility meter adopts photoelectric sensor BPV10

receive light scattering signals in air

after amplifying

filtering and A / D conversion to obtain digital signal. The system uses TMS320X2812

in order to improve data processing speed of system terminals

wireless data transmission is realized by using CC2530.Experimental results show that the system has advantage of high-precision

easy maintenance

and can meet requirements of meteorological observations.
