基于单片机的模拟智能灌溉控制系统摘 要随着农业生产水平的不断进展以及全球水资源的日趋紧张，世界各国都在积极探究行之有效的节水途径和措施。智能灌溉控制系统就是为了解决水资源不足、提高灌溉效率而进展起来的。本文讨论的单片机智能灌溉控制系统，是对土壤的温湿度进行实时监控，参考实际温度值设定适宜的湿度下限值，并根据设定的湿度值进行相应的灌溉。 该智能灌溉控制系统以 STC89C52 单片机为核心，主要由温湿度传感器DHT11 模块、按键输入模块、显示模块、水泵模块等组成；软件选用 C 语言编程。该系统的功能是：根据土壤湿度传感器检测到的土壤湿度，若检测到的土壤湿度值低于系统所设定的最低湿度值，系统则自动启动系统，进行灌溉。通过对硬件实物的测试，系统能够比较成功的实现目标功能。【关键词】单片机；传感器；LED 显示；水泵；灌溉Simulator smart irrigation control system based on single chip microcomputer AbstractAs the level of agricultural production and the continuous development of global shortage of water resources, countries in the world are actively exploring effective ways and measures for water conservation. Intelligent irrigation control system in order to solve the problem of water resources,improve the efficiency of irrigation and developed. This paper studies theintelligent irrigation control system, temperature and humidity in the soil was monitored in real time, refer to the actual temperature value setting and humidity limit appropriate value, according to the set humidity value for the corresponding irrigation.The intelligent irrigation control system based on STC89C52 single chip microcomputer as the core, mainly by the temperature and humidity sensor DHT11 module, key input module, display module, pump module; softwareused C language programming. The function of this system is: according to thesoil moisture, soil moisture sensor to detect soil humidity, if the detected valueis lower than the lowest humidity system sett...
