Abstract

A data transmission system for an irrigation system which comprises at least one field sensor collecting field data, at least one field monitoring station in communications with the at least one field sensor and a control unit in communications with the at least one field monitoring station over a remote communications link. The field data collected using the at least one field sensor is transmitted to the at least one field monitoring station. The field data is transmitted from the at least one field monitoring station to the control unit at a field data transmission interval adjusted according to a likelihood of an upcoming irrigation need determined based on the field data collected by the at least one field sensor and the control unit generates irrigation instructions based on the field data. An automated irrigation system and a method of performing data transmission for an irrigation system are also provided.
