GSM and Arduino Based Smart Circuit Breaker

A circuit breaker is an automatic electrical switch that protects a circuit from harm brought on by overload or short circuit. Linemen might suffer catastrophic electrical accidents when operated manually during maintenance time because of a lack of communication and coordination between the maintenance team and the personnel of the electric substation. The breaker can be set up so that only persons with a password and authorization can use it in order to reduce such accidents. We have created a circuit breaker (CB) that uses OTP as the key to operate the circuit breaker using a GSM module.
