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 mai...
