The project, "Theft Power Identifier and Overload Detection Using Differential Current Sensor," is designed to identify and mitigate unauthorized power consumption in real-time. It employs Arduino as the master controller, interfaced with two current sensors to monitor normal and suspected theft load currents. When a differential current indicates theft, a relay disconnects the unauthorized load, ensuring system integrity. An ESP8266 module transmits the current data to the Blynk app, where users can visualize load parameters and receive instant alerts upon theft detection. This system enhances power management and safety by addressing unauthorized power usage and overload scenarios effectively.
