Design and implementation of a computer interacted smart home system based on PLC

In this study, a smart home automation system has been developed to automatically achieve some activities performed frequently in daily life to obtain more comfortable and easier life environment. In the system developed, terminals and other components are controlled and observed via a computer interface using a programmable logic controller (PLC). Thus, some devices used in the system are easily accessed over the computer and status variations of them are successfully monitored on the interface. Additionally, several operations are also controlled and monitored over the user central control unit such as main entrance control, switch on or off the electricity connection, open or close the water and gas valves, turn on or off the thief control system, garage door control, lighting and heat control of the each room. Thus, a comfortable and interactive automation system has been developed. Test results of the system have shown that it can be easily used for the smart home automation applications.
