Since the late 1920's possibility of commercial hydroponics was testified practically. Hydroponics is used as environmentally friendly agriculture production system recently with high effectiveness. Now that existing irrigation control systems such as time control or solar radiation control cannot satisfy stable water content in root substrates, the needs for new irrigation system keep increasing. In this paper, we proposed environmentally friendly automatic irrigation management system by employing automation system based on electronic control system, which could solve problems based on manual irrigation management system. In addition, it suggested to be applied to any crops and will be able to overcome existing limit in irrigation by measuring the water content of root substrate in realtime.
