As a contribution in developing smart universities and achieving economy and comfort in terms of water-labor-saving as well as, improved water-energy efficiency, the present work provides both a conceptual design and a blueprint for practical implementation of wireless standalone solar powered smart irrigation control systems for managing water using in green areas of smart universities. The proposed system design consists of five sub-modules, each of which is planned to be standalone solar powered and wireless controlled. The module consists of sensor, main control unit, actuator, local water well monitoring and managing, as well as, to supervisor's wireless module for data recording and remotely monitor the green area state, in addition, monitor the irrigation activity. Wireless communication technology is applied to transmit data between these five sub-modules. The microcontroller based main control unit module is designed and programmed with control algorithm developed to process and analyze acquired data, predict the atmosphere state and take decisions based on the day time (morning/evening) condition, available volume of water in the well and soil state (temperature and moisture). If a specific treatment is required, decision is taken by the microcontroller and proper treatment is sent wirelessly to actuator modules to implement the decision process.
