Abstract: As monitoring and controlling the various electric and electronic home appliances based various sensors in real time by using programmable logic controller (PLC) has been adapted in the present work using renewable (solar) resources. The real time system is developed effectively and efficiently. The concept of smart home system is to connect all the blocks and devices to a controller so that they can be controlled from anywhere and react to one another.
