GSM Based System Design for Home Automation and Security

The security of a home can be improved if timely warning is available to the home owner, when he is away. GSM Technology and its extensive use as a popular communication device, in the form of cell phones, offer an opportunity. The technology could be used in many innovative ways to accomplish the task.In this project, the use of sensors and actuators combined with this technology has been the hallmark. In the events of detection of: smoke, natural Gas leak (Methane), intrusion through doors and or windows an SMS to a designated cell-phone is sent to the home owner/ resident. In case of intrusion a snapshot is automatically taken through a CCTV Camera. Capability to remotely (through cell-phone) switch on/ off the lights and an exhaust fan has also been built.
