摘要
本文结合节水园区与生态试验场的自动灌溉及数据采集系统的工程实际,采用AD590温度传感器检测温度信号,引入了1/64选通器对温度信号进行片选,在小投资前提下,实现了多达几百点温度的精确测量。
Combined the auto-irrigation system and data collection system in the experimental station for water-saving and agro-ecology water-saving park ,the temperature sensor AD590 and the 1/64 signals selector adopted in these system are introduced. On the premise condition of the lower cost, the measuring precision is improved mostly ,and the measurement of temperature for several hundreds of points is came true accurately.
