基于STC89C51单片机的智能电热水器的设计

摘要

本设计采用STC89C51单片机为核心来设计智能电热水器。本设计也对单片机控

制电热水器实现智能化的可能性进行了分析，利用温度传感器、和继电器等来完成本

设计。在硬件设计方面，主要对单片机最小系统及其扩展、电源电路、键盘显示及接

口电路、水温检测电路、报警电路进行了详细介绍。还详细介绍了设计中应用到的主

要芯片的性能和特点，包括STC89C51、DS18B20等。在软件设计方面，采用C语言

编程。

该智能电热水器设计完善，实现方案简单易行。采用软件设计来控制，可以实现

智能检测水温，智能加热，并且提高了整机的可靠性及准确性。
