Model no:161A The main objective of the project is to develop a circuit breaker which can be controlled remotely using cell phone. A unique password must be entered through the keypad of cell phone to activate/deactivate the circuit breaker. Each key of the password is identified with a frequency which is decoded to digital code through DTMF (digital tone multi frequency) decoder and that code is fed to a microcontroller which is programmed to recognize the code for operating the circuit breaker duly interfaced through driver IC for the load.
