摘　　要：该文设计了一种基于单片机的温、湿度控制的人造气候小系统。该系统以单片机为核心控制部件,采用数字式温度传感器DS18B20芯片采集温度、稳定性好的湿度传感器HI H-4000采集湿度。单片机将采集的各传感器的输出数字信号与预先设定的温、湿度进行比较,来调节小范围的湿度值和温度值。通过使用PROTEUS软件进行实时仿真,看到了温、湿度调节的作用,构建了一个宜人的气候闭环控制小系统。An artificial climate system was designed,which can control temperature and humidity based on AT89C51.The single-chip computer is the main control component.The digital temperature transducer DS18B20 is used to gather the temperature,and the humidity transducer HIH-4000 is used,which has a good stability to gather the humidity.Using the single-chip computer gathers all the transformation signals out of the transducers,which are compared with the default temperature and humidity to adjust the temperature and humidity.The function of adjustment by using the PROTEUS software is obvious to simulate and establish a closed-loop control and comfortable climate system.
