| 摘 要： | 利用ADS90温度传感器的特性，提出了一种既方便又实用的“保温杯”设计思路。可将温度示数直接转化为输出电压量，再运用桑成运放、比较器和二极管来控制水温，使之保持在40℃～70℃。

| Abstract: | Based on the characteristic of temperature sensor AN590,the design of ＂Heat Preservation Cup＂ for both convenience and application is proposed.The value of temperature can be directly converted into the output voltage, then by applying integration amplifier, comparator and diode the water temperature can be controlled in the interval of 40 ℃～70℃. |
