Sistem Monitoring PLTPh Turbin Pelton dengan Menggunakan Node MCU ESP32 Berbasis Internet of Things (IoT)

Abstract

The monitoring system based on the Internet of Things plays an important role in helping and simplifying human work in monitoring PLTPh. In this study, a current and voltage monitoring tool for PLTPh based on the Internet of Things (IoT) was developed. This system is designed as a remote monitoring solution. This monitoring system is equipped with Arduino Uno and NodeMCU installed and also includes the program. The ACS712 sensor is used as an input sensor that can measure the voltage and current values on the PLTPH, IR Sensor is used to measure the generator rotation speed in RPM units, YF0s210 waterflow sensor is used to measure the discharge of water that comes out and the sensor readings are received by Arduino Uno in the form of data. Monitoring remote sensor readings by a web server by connecting the internet to the NodeMCU ESP 32 as a data receiver from Arduino to a smartphone. Based on the test results, the monitoring system tool can be accessed using a cellphone / laptop using a web server. From the test results obtained the highest voltage value with a variation of DC lamp load obtained the result of 11.95 V, the highest current value of the variation of dc lamp load obtained the result of 0.13 A, the highest power value at each load is 1.36 watts, water discharge is 2 L/s, and the highest generator rotation at each load is 1295 Rpm.
