Arduino Platform for Optimized Irrigation in Strawberries Fields

The paper is focused on the development and implementation of an autonomous and automatic system for irrigating in a strawberry field. For this purpose a smart irrigation system using Arduino was created. The software takes into account information related to water tank level, soil moisture and solenoid valve position, while providing farmers with daily information about the state of the culture. The output values of the sensors transmitted to the microcontroller are analyzed and, depending on the threshold imposed by the user, a decision is made whether to water the plants or not. Thus the microcontroller gives the command to open or close the solenoid valves. The water level in the tank used to supply the installation is also monitored using an ultrasonic sensor. System information such as date and time, soil moisture in the three areas, the condition of each solenoid valve and the amount of water in the tank are displayed in real time. The results yielded by different tests confirmed the functionality of the irrigation system, which remained in operation throughout the season.
