基于AT89S52的室内湿度测控自动化模块的设计

Design of Indoor Humidity Monitoring Automation Module Based on AT89S52

许多精密仪器设备对运行环境的要求较高。为了保持它们正常运作,提升机器的运行效率和稳定性,其室内环境湿度必须控制在适宜范围内(40%~60%RH)。基于单片机AT89S52,以电容式相对湿度传感器HS1101作为前端检测,用Keil Uvision 3编程软件编写控制程序和电路设计软件Multisim 10.0进行电路设计,最后在调试软件Protues 7.5进行系统仿真调试。

Many precision instruments and equipment have higher requirements for the operation environment. In order to maintain their normal operation, improve the efficiency and stability of the machine, the indoor environmental humidity must be controlled within the appropriate range （40% ~ 60% RH）. Based on the single chip microcomputer AT89S52, the capacitive relative humidity sensor HS1101 is used as the front end test. The control program and the circuit design software Multisim 10 are designed by Keil Uvision 3 programming software. Finally, the debugging software Protues 7.5 is used for system simulation debugging.
