综合实践项目名称 基于单片机的大棚温湿度设计 专业班级 电子 104 学生姓名 指导老师 2013 年 6 月 28 摘 要以 ATMEL S52 单片机为核心,并通过 DHT11 温湿度传感器的工作原理，实现了对当前环境中温度与湿度的测量，并且通过设置好的温度与湿度的上限、下限的值对当前环境下的温度和湿度实施监控，超过预警值则实施自动报警。该系统由温度传感器模块、湿度传感模块和液晶显示模块组成，应用温湿度传感器的工作原理对当前环境实施监控，定时采集数据传送给单片机，单片机根据温湿度传感器采集到的数据进行处理，再将接收的数据显示到 12864 液晶显示屏上，若是超过预期设置的上限和下限，采纳二极管模拟报警，由于制作和组合上的精细，使得本设计显得智能化、有用化。关键词：51 单片机；温度传感；湿度传感；12864 液晶显示AbstractThe design STC52 microcontroller core, and through DHT11 temperature and humidity sensor works to achieve in the current environment, temperature and humidity measurements, and a good temperature and humidity by setting the upper limit, lower limit value of the temperature on the current environment implementation of monitoring and humidity, more than the value of implementing an early warning alarm. The system consists of temperature sensor module, humidity sensing module and liquid crystal display module, the application of temperature and humidity sensor works by monitoring the implementation of the current environment, regularly collected data to the microcontroller, microcontroller based temperature and humidity sensor for processing the data collected, and then will receive the data to the LCD screen on the 12864, if more than expected to set the upper and lower limits, the use of diode analog alarm, due to a combination of production and fine, making the design is intelligent, practical.Keywords：51single-chip； temperature sensor；humidity sensor；12864 LCD目 录摘要.....................................................
