温室群全数字式温度和湿度综合控制系统

An All-digital Temperature and Humidity Controlling System Used in Greenhouses

应用计算机集散控制原理 ,采用新型的数字式温湿度一体化传感器 (L TM890 1)和一线总线结构 ,研制了一种适用于温室群的温湿度全数字自动监控系统。温湿度控制子系统使用大容量 EEPROM,可在 10

According to the principle of distributed microprocessor control system, a new microprocessor controlled temperature and humidity system, all digital system, was developed using a new type digital sensor of temperature humidity (LTM8901). A subsystem with EEPROM can set the temperature and humidity values and record their actual values per hour for 100 days. Because of its advantages of simple structure, being easy to maintain and good measuring controlling stability, this system is an ideal alternative to the analog temperature and humidity measuring controlling system.
