Abstract

Electricity costs in boarding rooms are often unfairly distributed because each room is charged the same amount, even though electricity usage varies. To solve this problem, a system was created to monitor each room's power usage more efficiently using Long Range (LoRa) technology. This system uses an ESP32 microcontroller, a PZEM-004T sensor, and LoRa, programmed with Arduino IDE. The sensor collects power usage data and sends it to the boarding house owner over the LoRa network, with accuracy close to 99% in three tests. The data is transmitted up to 150 meters with an RSSI of -107 dBm in non-line-of-sight (NONLOS) conditions and up to 600 meters with an RSSI of -111 dBm in line-of-sight (LOS) conditions. It is also connected to an Android app for easier power management and monitoring.

Abstract

Pengelolaan daya listrik di kamar kos sering kali menimbulkan ketidakadilan karena biaya listrik disamaratakan, meski pemakaian berbeda. Untuk mengatasi masalah ini, dirancang sebuah sistem pemantauan daya listrik dengan teknologi LoRa. Sistem ini memanfaatkan mikrokontroler ESP32, sensor PZEM-004T, LoRa, dan Arduino IDE. Data penggunaan daya listrik yang dikumpulkan oleh sensor dikirim ke pemilik kos melalui jaringan LoRa. Data penggunaan daya listrik dikirim melalui jaringan LoRa hingga 150 meter (RSSI -107 dBm) dalam kondisi NON-LOS dan 600 meter (RSSI -111 dBm) dalam kondisi LOS, kemudian diintegrasikan ke aplikasi Android untuk pengelolaan dan pemantauan daya listrik. Hasil pengujian menunjukkan akurasi 99%, menjadikan sistem ini solusi efektif dan efisien untuk pengelolaan daya listrik di kamar kos.   Abstract Electricity management in boarding rooms is often unfair because electricity costs are shared equally, even though each room uses different amounts of electricity.
