Home and office automation system-survey

In recent years it is witnessed that there is a significant progress in the automation of human activity. It is recognized in order to realize intelligent environments which are capable of detecting users actions and gestures so that the needed services can be provided automatically and instantly for maximizing the user comfort and safety as well as minimizing the energy. If a person enters into the room and sits/stands/lies down then the fan or AC should be automatically turned on. If a person comes and walks away or keeps roaming around, then he should not be turned on or off the electronic gadgets. The system will automatically turn off based on his activity. Thus we can save the energy.
