Surface The Evapotranspiration plays an important role in the design of the water balance in agricultural areas, and affects the irrigation scheme and management of water resources. The study focuses on estimating the reference of evapotranspiration (ETo) using data collected from both an Arduino-based system and a traditional weather station. The Arduino (UNO) system was tested in seven days using the DHT11 sensor to measure temperature and humidity, which shows real-time temperature data on the LCD screen. In comparison, temperature data (maximum and minimum values) from the Mosul weather station were used to calculate ETo, which is a temperature model using the Hargreaves method operated with minimal input data. The results showed that the ETo values increased with rising temperatures. The curve ETo tendency starts at a low point at the beginning of the year due to cold, rainy conditions, then increases gradually to the maximum value in July due to the hot season and then gradually decreases to a lower less at the end year. This research indicates that in areas where wide weather data is not available, an Arduino-based layout can effectively act as a compact weather station and provide sufficient data for reliable ETo estimates.
