GSM Based Home Automation

A GSM based home automation system is designed to control home appliances through Arduino Uno microcontroller & SIM900 GSM/GPRS shield. The user can assure the safety of his/her house from anywhere of the world under GSM coverage network. It is possible because GSM technology has large baud rate. This system is implemented with four loads and a temperature and humidity sensor. The control of the home appliances is done through the SMS sent through the GSM network and the hardware. This system uses mobile phone as controlling device which control the home appliances by sending SMS and receiving phone call. The system can detect the undesirable temperature rising & control that temperature by activating or deactivating the DC fan. This system is also convenient for handicapped people for ease of controlling the whole system.
