Abstract
Gaza Strip is a small region with limited agriculture land and water resources. Greenhouse technology allows farmers to optimize the use of this land. In this paper a computer-based control and monitoring system is designed and tested to automate drip irrigation. The model greenhouse can be used as a prototype where several sensors are connected to an acquisition and control system using a PC and a data acquisition card. The designed system can be used as a stand-alone system by lay farmers with no technical background where they can command full control through a screen command. The system is set up to handle several crops by using a user screen to adjust certain parameters on the front panel. A web server enables users to remotely monitor and control the greenhouse through VI's from any place in the world with internet access. Moreover, the system periodically generates alarms and automatically sends emails to notify users of the conditions inside greenhouse.

Summary
Greenhouse agriculture became popular in the last three decades. Greenhouse controlled environment provides a golden place to grow crops out of season and increase the crops' s productivity [1]. Greenhouses are translucent glass or plastic construction for hasting crops growth [2] They allow for more effective use of water and daylight. Greenhouse technology has been utilized for the last three decades but with no monitoring systems, no control, and no data records of over-pumping and/or over-applying irrigation water. This process sometimes consumes more water and sometimes irregularity in watering causes the crops to dry. Water deficiency can slow growth rate and lead to lighter weight fruit This problem can be solved using automatic drip irrigation system in which the irrigation will take place only when the crops need to be watered. This paper divides the automation process into two parts: The first involves studying the basic components of irrigation system, while the second covers the design and implementation of the control circuitry
