Home automation system makes the operations of various home appliances more convenient and saves energy. With the energy saving concept, home automation or building automation makes life very simple nowadays. It involves automatic controlling of all electrical or electronic devices in homes or even remotely through wireless communication. Centralized control of lighting equipments, , security systems, kitchen appliances and all other equipments used in home systems is possible with this system.
This system is mainly implemented by sensors and controlling devices as shown in the figure. The sensors detects light, motion, temperature and other sensing elements, and then send that data to the main controlling devices.
Controllers may be personal computers/laptops, touch pads, smart phones, etc., attached to the controlling devices like programmablelogic controllers that receive the information from the sensors. The programmable controller allows to connect various sensors and actuators through various input and output modules whether they are analog or digital.
