This paper presents a method for users to control their home and office appliances remotely using a mobile phone. This is borne out of the desire to minimise accidents and prevent damage to electrical appliances as a result of not switching off electrical appliances such as pressing iron, electric heater, etc, which can result in fire incidence and damage. The system provides the ease of turning on/off electrical appliances with its attendant safety. The access control is achieved by sending a DTMF code from the user mobile phone to the device mobile phone receiver. The received DTMF code is then decoded by the DTMF decoder which interfaces with a PIC Microcontroller to process the signal and control the appliance with the aid of a relay. The switching system presented in this paper will enable the switching of electrical appliances with AC load of 220V±5% supply from a mobile phone by simply issuing a command through the phone’s keypad to the system. This saves time used in switching ON or OFF the electrical appliances manually since the electrical appliance can be controlled from this remote system.
