The biggest problem in agriculture is the insufficient amount of water. Sowing cannot be done in the fields due to water scarcity. Some fields become barren land due to excessive irrigation. For these reasons, it is important to use water wisely. In the study, irrigation of tomatoes seed is controlled with fuzzy logic. The use of water is made automatically according to the humidity, temperature and soil moisture of the air. The study was carried out in two stages. First stage; The irrigation system is designed in the MATLAB program. For this, temperature, humidity and soil moisture were used as three inputs. Irrigation time was calculated as output. All inputs and outputs are set to low, medium and high. In the second stage; equal amounts of tomatoes seeds were planted in two separate containers. Normal irrigation was done in the first pot. The control of irrigation in the second bowl was made with fuzzy logic. All data are shown on the screen and recorded for 1 minute. As a result of the study, 22500 milliliters of water were used in normal irrigation, and 10410 milliliters of water were used in a fuzzy logic-controlled circuit. As a result, a water saving of 53.77% was achieved. Arduino microcontroller is used for control. The code was written for the fuzzy logic control circuit simulated in the Arduino microcontroller MATLAB program to work. At the same time, temperature and humidity sensors are connected to the Arduino microcontroller. Incoming data is remotely monitored and controlled by a modem connected to the microcontroller. When the records in the database are examined, 83% energy was saved with lighting algorithm and energy flow control algorithms.
