摘　　要：鸡舍温度对鸡的产蛋量、蛋的大小和蛋壳厚度都有不良的影响。鸡舍的空气湿度对鸡体蒸发散热和非蒸发散热都有影响。为此,提出了基于ATmega16、计算机及SHT71组成的鸡舍温湿度检测控制系统。它可以利用SHT71完成对鸡舍环境温度和湿度的自动检测,把数据通过RS485传输到计算机,通过计算机进行相应的数据处理,并控制风扇和水帘,来对鸡舍的温湿度进行自动调节。最后,利用PROTEUS对整个系统进行仿真调试。The temperature of a henhouse has a bad effect on the egg production, egg size and eggshell thickness of the hen. The humidity of the henhouse can affect the evaporation and the non- evaporative of the Chicken body. I put for-ward a proposal that is making a temperature and humidity detection and control system basing the ATmegal6 and computer and SHT71. It can complete the automatic detection of the temperature and humidity by using the SHT71, and it can also transmit the data to computer by the RS485, and handles the data by the conputer, at last it control the fan and the water screen to complete the automatic adjustment of the temperature and humidity of the henhouse. At last I make a simulation to the entire system by the software named PROTEUS.
