Name & Surname:
The Pivot Optimiser
The Pivot Optimiser is an IOT monitoring and control system for irrigation center pivots and pumps. It performs local control functions (which keep working with no internet connection) and transmits all measured data to a webserver. Settings are entered on the webserver. The system saves energy (typically 25%) by controlling the pump pressure as the pivot moves up and down hills. Pump efficiency is continuously monitored allowing wear to be detected and maintenance scheduled. Physically it consists of a main unit (electronics plus firmware) installed in the pump house with a radio link to remote units installed on the pivot. The remote units are powered by a solar panel and measure the pressure of the pivot using pressure sensors. The system monitors water use and is a tool for farmers to reduce water consumption. SMS alerts are set to operators.
