Abstract

The Archimedes turbine is widely considered for microhydro power plants because it can operate at low head conditions, has a relatively simple construction, and is suitable for canals or small streams. This study aims to design and test an Internet of Things (IoT)-based monitoring system to read the voltage, current, and output power of the Archimedes turbine generator. The system uses an INA219 sensor, an ESP32 microcontroller, a Wi-Fi connection, and a Blynk dashboard. Testing was carried out under two conditions, namely no-load and with load. The no-load voltage is in the range of 14.5–15.6 V. After the load is connected, the voltage is in the range of 9.707–10.582 V, the current is 0.228–0.333 A, and the measured power is 2.073–3.511 W. Based on the midpoint of each range, the loading reduces the voltage from 15.050 V to 10.145 V or approximately 32.6%. These results indicate that the monitoring system is capable of recording changes in the generator's electrical characteristics due to loading. However, turbine efficiency evaluation still requires discharge, head, rotation, and torque data, while power consistency needs to be verified using synchronous voltage and current sampling.
