摘　　要：能见度仪光学器件的温度稳定性以及光学镜头与外部的温差都将直接影响能见度仪的精度。因此,必须对能见度仪内部温度进行检测和控制。本文介绍了TMP05数字式温度传感器及其菊花链式多点测温原理,并且给出了TMP05的菊花链式多点测温在能见度仪温度测量中的软硬件设计。Because of using optics sensor and working under external environment condition, the precision of the visibility meter was affected by the temperature stability of the optics sensor and the difference between the temperature inside and outside the meter. So it is very important to measure and control the temperature inside the meter. For this reason we introduce a kind of digital temperature sensor TMP05 and its daisy-chain for multi-point temperature measurement, and then we design the hardware circuit and software flowsheet for the daisy-chain multi-point temperature measurement, which was used for the temperature measurement of visibility meter.
