Appliance Control using Short Message Service (SMS)

Abstract: This paper describes the design and implementation of a GSM-based password-protected control system for electrical home appliances that allows for remote control. The GSM module is used to receive short message service (SMS) messages from the user's mobile phone, which automatically allows the controller to take further action such as turning on or off home appliances such as lights, air conditioners, fans, water pumps, door locks, TVs, and so on. The system's hardware was created using an Arduino Uno board, GSM modules, switching relays, and other readily available electronic components. The Arduino IDE was used to create the driving software. When only the user sends the SMS to the controller at home with the exact password, the system is activated. When the microcontroller unit receives an SMS command, it automatically decodes it and controls the electrical home appliances by turning them ON or OFF based on the user's instructions.
