Prototype and Validation of an IoT-Based Voltage and Temperature Monitoring System for Remote ISP Point-of-Presence (POP) Infrastructure

Monitoring electricity and temperature is crucial for maintaining PoP server performance. This research developed an Internet of Things (IoT)-based tool using a NodeMCU ESP32 to directly monitor these two factors. The ZMPT101B sensor measures electrical voltage, while the DHT22 sensor monitors the temperature of the room and server rack. Information obtained from the sensor is sent in real time via a Telegram Bot to the administrator. This tool is particularly useful for PoP located remotely, as it makes it easier for administrators to monitor server conditions and prevent damage. The use of the Arduino IDE is also essential in the development of this tool for uploading programs to the microcontroller. The results of this research provide a practical solution for maintaining server and ensuring internet network stability. The urgency of this research lies in the growing need for reliable and efficient remote monitoring systems to maintain stable internet network operations, especially at PoP locations far from data centers. Undetected power outages or temperature fluctuations can cause significant server damage and result in a decrease in service quality for users.
