摘要
本文介绍了一种应用LM35温度传感器开发的温控系统,重点阐述了系统结构、工作原理、采样值量化。同时对LM35传感器特性、系统硬件电路设计、软件设计也作了介绍。该系统体积小、成本低、工作可靠,具有很高工程应用价值。系统稍加改动或扩展,还可以完成温度测量等功能。
The article introduces a temperature control system which is based on LM35 temperature sensor. The author emphasizes particularly on the structure of system, working theory and the measurement of sampling value. What's more, it includes the characteristics of LM35 temperature sensor, the circuit design of system hardware and the design of software. The system has many characteristics―little volume, low cost and working stability, and it is very useful to the engineering application. This system also can accomplish the function of measuring temperature if we change or extend it slightly.
