Monitoring and Control System of Center-Pivot Irrigation System throughInternet

Abstract

The center pivot irrigation system is one of the most modern irrigation systems used in the modern world. Water distribution in this system is carried out by a rotary structure with a water pipe with many sprinklers distributed along the pipe. The structure of the system rotates in a round shape to carry out the irrigation process. This system is controlled through a control panel attached to the center of the rotor body (pivot point). The aim of this thesis is to design a monitoring and control system for the center pivot irrigation system through the Internet. The control system consists of temperature and humidity sensors of the surrounding medium, water pressure sensor in the main pipe and anemometer to measure the wind speed in the field as well as a sensor to determine the direction of the rotor body in the center pivot irrigation system. The system is also controlled by an electric switch (relay) to control the operation and shutdown of the system as well as running and stopping the water pump. The control and monitoring process is done via a web page connected to a server using the controller (ESP32) where this controller is connected to a wireless network (Wi-Fi). Aprototype of the system was implemented and the effectiveness of using the web page to send control signals and receive readings from the sensors was verified.
