Greenhouse Temperature and Humidity Process Control System Based on Experimental Data

The necessity of parameter self-setting in greenhouse temperature and humidity process controlling system is discussed. A suitable for greenhouse humidity control system based on experience data is suggested. The system hardware employs a new-type integrated digital sensor of temperature and humidity (LTM8901 ). A new microprocessor-controlled C8051F023 temperature and humidity system is developed in this work. A subsystem that has large capacity Flash memory which can set temperature and humidity values and record their actual values in one year per hour. They can fully control without human interference in one year. 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. The system is very useful for other environments for auto-controlled temperature and humidity.
