Electrocution is a major fatal issue faced by electricians worldwide. A Circuit breaker is a device for automatic switching of electrical devices against overload and short circuits. However, advancements in technology allow for a more sophisticated approach: the cloud-based circuit breaker with a microcontroller and sensors for monitoring the line current and voltage levels. This system switches OFF the affected line when an electrical wire becomes defective, and the lineman may safely repair it. This design integrates real-time monitoring, remote control, and internet connectivity, enhancing electrical safety and offering valuable features for modern applications. At the heart of this design lies a microcontroller (Atmega328) and Esp8266_01(Wi-Fi Module). This tiny computer chip continuously monitors the circuit using current and voltage sensors. By regulating the power supply on the electrical lines, this system protects the safety of the lineman and reduces the risk of electrocution injuries.
