Inovasi Charging Controller Dengan Metode Hybrid Plts dan PLN Menggunakan Coin Acceptor Sebagai Metode Pembayaran Berbasis Internet of Things

Abstract

A charging controller innovation has been successfully designed with a hybrid PLTS and PLN method using a coin acceptor as an internet of things (IoT)-based payment method. This study aims to develop a charging controller innovation with a hybrid PLTS and PLN method, as well as the integration of a coin acceptor as an IoT-based payment method. This tool creates a system that is efficient, easily accessible, and supports the use of renewable energy. The system is designed using NodeMCU ESP32, LCD I2C 20X4, coin acceptor, PZEM-004T sensor, relay, 12 V adapter, and solar panel. Testing shows that the 12 V adapter functions stably with a deviation of only 0.4%. The coin acceptor successfully detects Rp1,000 coins with an accuracy level of 100%. The solar panel produces an average voltage of 17.24V, a current of 0.00081A, and a power of 0.01445W. Overall system testing shows that for Rp1,000, consumers get 100 kWh, and the system can measure the power consumption of connected devices. The study lamp has the lowest power consumption of 0.8W, while charging cellphones and laptops has the highest power consumption of 49.4W.
