Abstract

This paper addresses the development and the implementation of a wireless sensor network for in situ streamflow estimation in irrigation channels using gauging station network and transmission technologies. For short-range data transmission we used technologies under ZigBee ® protocol, and for long-range transmission we used FHSS technology. We show in detail the hardware and ad hoc software development. The information is stored in a MySQL database and hosted on a local server for access through a Web platform. The data records are displayed in tables and Google Maps ®for its spatial location. In preliminary tests, the sensors proved to be highly robust in the communication, as well as in speed, usability and accessibility to the system.
