摘要

In modern cities, public places such as streets, parking lots, shopping malls, airports, and railway stations must provide mobile charging stations and EV charging stations. Power waste and misuse are on the rise. The situation is more complicated as electricity generation and distribution become more expensive. There is extensive research and products on electrical smart sockets or plugs in the market today that support Wi-Fi, Bluetooth, and Zigbee connectivity and provide several features. However, only a few of them can measure the quality of the load, which is a very useful electrical characteristic to identify unbalanced loads in the house or factory. This paper aims to contribute toward building smart homes and cities and primarily focuses on the design and implementation of cost effective, future ready, secure wireless smart sockets that are capable of monitoring electrical parameters and controlling output power based on the quality of the load by measuring power factor, reactive power, and active power. The system is implemented using an advanced ESP32FC6 RISC-V-based wireless microcontroller, a high-performance CS5490 power meter IC using a shunt resistor current sensor, and a high-performance TRIAC-based solid state relay capable of handling loads up to 15A peak current. The system developed thus, demonstrates programmability, accuracy of captured electrical characteristics, and quality of load connected.
