中文摘要:
      基于STC89C52单片机设计的智能温湿度检测系统,硬件部分包括主控芯片、DHT11传感器、LCD1602液晶显示、按键和报警。软件部分由C语言编写。在单片机的控制下,温湿度传感器将检测到的温湿度参数,通过端口送给单片机进行处理,同时在LCD1602液晶显示器上进行实时显示。用户可以通过按键电路设定温湿度的最高、最低阈值,一旦温湿度的值超过阈值,即可发出声光报警告知管理人员。最终,在Keil环境下完成了C语言程序的编写,并且联合Protues软件完成了仿真,而且进行了电路板的焊接,软硬件的调试,能够准确测量环境的温湿度,实现超限报警功能。
英文摘要:
      The design is based on STC89C52 microcontroller design of intelligent temperature and humidity detection system, the hardware part, including the master chip, DHT11 sensor, 1602 LCD display, buttons and alarm. The software part is written in C language. Under the control of the microcontroller, the temperature and humidity sensor will detect the temperature and humidity parameters, through the port to the microcontroller for processing, while the LCD1602 liquid crystal display on real time display. And the user can set the temperature and humidity through the key circuit of the highest and lowest threshold, once the value of temperature and humidity exceeds the threshold, you can inform the sound and light alarm management. In the end, the design in the Keil environment to complete the preparation of the C language program, and the joint Protues software to complete the simulation, and the circuit board welding, hardware and software debugging, can accurately measure the environment temperature and humidity, and can achieve beyond threshold alarm function.
