The imbalance between population growth and agricultural production increases the demand for food, making irrigation efficiency essential for food security. This study develops an automated irrigation system based on the Penman-Monteith method to calculate evapotranspiration and irrigation pulse. An experiment compared methods based on evapotranspiration and accumulated radiation, showing the former was 7% more water-efficient. The system uses an ESP32 microcontroller, radiation, humidity, and temperature sensors, promoting water savings and better agricultural management.
