Power Visualization Smart Socket With Security Functions Based on ESP32-S Microcontroller

This paper presents one system utilizing a microcontroller chip (ESP32-S) and a Hall effect-based current sensor (ACS712) to monitor the power consumption of the household sockets. LED light and OLED monitor display real-time usage status of various loads, providing users with instant insights into socket usage. The system uploads household electricity usage records to ThingSpeak for further analysis and tracking based on the ESP32-S's Wi-Fi connectivity. Eventually, ThingSpeak notifies users about mitigating potential accidents and enhancing the security features of the power visualization smart socket in cases of power overload.
