Water level monitoring system are widely used inside and outside currently. Level detection is the level of data collection, storage, transmission, processing and other technology integration. Level detection methods are many, such as artificial detection, sensor detection and so on. This article is based on a pressure sensor to achieve the level controller design method, the controller STC89C51 microcontroller as the core, supplemented by peripheral hardware circuit to achieve control requirements. This paper describes the overall design scheme, and then focuses on the role of various functional modules and implementation. Finally, proteus simulation software is introduced.Keywords: level detection single chip microcomputer control sensor  PAGE \* MERGEFORMAT ii STYLEREF 标题 1 \* MERGEFORMAT 目 录 STYLEREF 标题 1 \* MERGEFORMAT 第五章 Proteus仿真软件介绍 i目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc358283565 第一章 绪 论 PAGEREF _Toc358283565 \h 3 HYPERLINK \l _Toc358283566 1.1 液位自动检测的现状及发展趋势 PAGEREF _Toc358283566 \h 3 HYPERLINK \l _Toc358283567 1.2 课题背景及研究意义 PAGEREF _Toc358283567 \h 3 HYPERLINK \l _Toc358283568 1.3 方案规划 PAGEREF _Toc358283568 \h 3 HYPERLINK \l _Toc358283569 第二章 单片机最小系统设计 PAGEREF _Toc358283569 \h 3 HYPERLINK \l _Toc358283570 2.1 单片机最小系统的功能 PAGEREF _Toc358283570 \h 3 HYPERLINK \l _To
