摘要
基于LM35传感器设计了数字显示的测温系统。介绍了该系统的构成、基本原理及软、硬件设计,讨论了LM35的温度特性。结果表明:该系统实际测温范围为0～100℃,3位整数显示,测温相对误差为±1.0%。
The temperature measurement system with digital display was designed based on LM35 sensor. The composition, basic principles, software and hardware design of the system were introduced. And the temperature characteristics of LM35 were diseussed. The results of tests indicated that its measuring range was 0 - 1130 ℃ with the relative error of ± 1.0%.
