基于AT89C51的湿度检测系统设计与研究

Design and research of the humidity measure system based on the AT89C51 monolithic microcontroller

人工气候室如今已广泛应用于工农业生产的许多方面。在人们的日常生活中,人工气候室的湿度参数直接影响着人的居住环境和身体健康。本文以计算机智能监控人工气候室的研究为背景,针对目前在湿度检测方面存在的问题,对湿度检测系统的测量原理和单片机AT89C51的硬件控制电路以及湿度的控制方法进行了研究并设计出这一系统的实现方案。实验结果表明该系统的可靠性高,而且易于控制,具有较好的实用价值。

Nowadays, the artificial weather room has already been extensively applied to a lot of respects of the industry and agriculture produce. In daily life, the humidity parameters of the artificial weather room directly influence people＇ s health and living environment. This text regards research of the computer intelligence supervises and control in artificial weather room as the background, aiming at the question existing in humidity measure at present, studies the measuring principle, the controlling circuit of hardware of AT89C51 and the humidity control measure and then designed this systematic realization scheme. The results of the experiment shows that the system has high reliability, easily contorl and is valuable in practical application.
