Rancang Bangun Alat Bantu Pengisian Token Listrik dengan Pengendali Utama Mikrokontroler Berbasis Internet Of Things

Abstract

Prepaid electricity payment systems using tokens are becoming increasingly popular, but token entry often requires physical presence at the meter location, which can be difficult to access, leading to inconvenience for users. This study designs a token entry aid based on the Internet of Things (IoT) using an ESP32 microcontroller, enabling remote token entry without physical presence. The system is equipped with 12 relays for token input and an ESP32-CAM for visual documentation. A web interface is used for real-time control and monitoring. Testing shows the device can enter tokens with high accuracy and efficiency, improving user convenience in managing prepaid electricity tokens. This innovation makes the token entry process easier and accessible from anywhere. Further development could expand the application of this system on a larger scale. The system can also be integrated with other technologies to enhance its functionality. Additionally, the device can be customized to meet specific user needs in various environments.
