基于单片机的智能温室温湿度控制系统的设计 摘要：在农业生产中，温室大棚的应用越来越广泛，为人们创造了更高的 经济效益。在温室大棚中，最关键的是温湿度控制方法。传统的温湿度控制方 法完全是人工的，不仅费时费力，而且效率低。本文旨在论述一种温室大棚温 湿度控制系统的设计，该系统主要由单片机AT89S52、温湿度传感器DHT11、 无线通信模块nRF2401、液晶显示LCD1602等组成。采用温湿度传感器DHT11 来测量温湿度，它的精确度高，而且DHT11直接是输出数字信号，可直接与单 片机相连。通过无线传感器nRF2401来进行信号传送，这样能够降低布线的麻 烦。显示部分使用的是 LCD1602 来显示温湿度。本系统的核心是单片机 AT89S52，接收传感器所测的数据并处理，然后执行各种操作。本系统智能度 高，可靠性高，系统工作稳定，且综合性价比较高，具有较大的市场应用前景。 关键词：单片机，温湿度控制系统，温湿度传感器DHT11，LCD 显示， 无线模块nRF2401 Design of temperature and humidity intelligent greenhouse control system based on SCMcontrol system based on SCM Abstract :In agricultural production, more and more extensive application in th gr nhouse, creat mor economic benefits for th people. In th gr nhouse, th most critical is th temperatur and humidity control method. Temperatur and humidity control of traditional methods is entirely artificial, not only time-consuming effort, and low efficiency. The system consist of the microcontroller AT89S52 ,digital temperatur and humidity sensor DHT11,wireless sensor NRF2401,LCD1602 and other components. To measure the temperature and humidity using temperature and humidity sensor DHT11, its precision is high, and the DHT11 is directly output digital signal, can b directlydirectlyconnected with th single-chip microcomputer. Through th NRF2401 to transmit signals, it can reduce the trouble of wiring. The display part is using LCD1602 to display the temperature and humidity. The core of this system is AT89S52, the measured sensor data received and processed, and then perform various operations. The system of high intelligence, high reliability, the system is stable, and the higher price, has great market prospect.
