This experimental study evaluated the performance of an Arduino-Based Watering System for monitoring soil moisture levels in agricultural crops, analyzing the results across different times and plants. The system utilized smartphones connected via Bluetooth to the Arduino device to measure soil moisture in four different plants at 30-minute intervals. Statistical analysis using the mean, standard deviation, and Kruskal-Wallis H test demonstrated no significant difference in the watering system's effectiveness when classified by time and plant type.
