Descripción:	The Class A Pan is widely used for estimating reference evapotranspiration (ETo), a key parameter in irrigation management. Traditionally, water level readings are taken using a micrometric screw, which requires daily manual collection and is prone to operational errors. This study proposes an automated approach using the VL53L0X sensor, integrated with an Arduino Uno platform, aiming to evaluate its feasibility as an alternative to the conventional method. The sensor operates with Time-of-Flight (ToF) technology, emitting an infrared beam that reflects off an object and returns to the receiver, allowing precise distance measurement. To simulate the tank’s stilling well, a 500 mL graduated cylinder was used with a floating white Styrofoam disc as the reflective surface. The initial point was set at 60 mm, and tests were conducted up to 70 mm, with 100 readings per level across four repetitions, totaling 4,400 measurements. Data were stored in Excel spreadsheets and statistically analyzed using arithmetic mean and standard deviation. Results indicated good sensitivity and repeatability of the sensor for millimetric variations. Automation enables integration with Internet of Things (IoT) systems, allowing remote data transmission, which is a significant advantage for producers with large cultivated areas. It is concluded that the VL53L0X shows potential to replace the micrometric screw, provided it is validated under real field conditions.
