                 Infrared telemetry for data acquisition and telecontrol

                                in automatic irrigation scheduling

                           Abobaker S. Ahmed and Ahmed I. Al-Amoud

             An infrared telemetry systems was employed in a project of automatic irrigation scheduling based on soil moisture sensing. It was used to transmit continuous soil moisture potential from a remote field planted with wheat to base station for analysis. In the base station, where a microcomputer was housed, the field information was processed through water management software developed for this purpose to decide when to start or stop irrigation based on a predetermined threshold for soil water potential. When start or stop irrigation was decided by the computer, a telecontrol signal was sent through the infrared system to the pumping station to deliver water or to stop it.
