摘要
现代农业发展中，温室大棚栽培技术为高品质农产品的稳定供应提供了重要保障。传统温湿度调控依赖人工操作，存在效率低、精度差等问题。本文提出一种基于STC89C52单片机的智能温湿度控制系统，通过集成DHT11数字温湿度传感器、12864液晶显示屏及继电器模块，实现温室环境的自动化管理。系统实时采集环境数据并显示，用户可通过矩阵键盘设置阈值范围。当温湿度超限时，蜂鸣器触发报警，继电器联动LED指示灯模拟空调与加湿设备的工作状态。相较于传统方案，本系统具备成本低、稳定性强、操作简便等优势，可有效提升农作物生长环境控制的精准性与可靠性，助力农业生产的提质增效。Abstract
In the development of modern agriculture, greenhouse cultivation technology provides an important guarantee for the stable supply of high-quality agricultural products. Traditional temperature and humidity control relies on manual operation, which has problems such as low efficiency and poor accuracy. In this paper, an intelligent temperature and humidity control system based on STC89C52 microcontroller is proposed, which realizes the automatic management of greenhouse environment by integrating DHT11 digital temperature and humidity sensor, 12864 LCD display and relay module. The system collects and displays environmental data in real time, and the user can set the threshold range through the matrix keypad. When the temperature and humidity exceed the limit, the buzzer triggers an alarm, and the relay linkage LED indicator simulates the working state of the air conditioner and humidification equipment. Compared with traditional solutions, this system has the advantages of low cost, strong stability and easy operation, which can effectively improve the accuracy and reliability of crop growth environment control and help improve the quality and efficiency of agricultural production. 关键词
