Abstract :

                   Numerous studies have shown that smart homes or intelligent buildings can use energy more efficiently than traditional buildings. Thus, several researchers have advocated Building smart homes for reducing energy consumption. Almost proposed smart home architectures in the literature adopt the WSN (Wireless Sensor Network) as the dominant Technology. The WSN, rather than Wi-Fi, has been popularly employed for remote control and monitoring applications. Because it has a low cost and consumes little Power. However, several problems in the construction of smart Homes with WSNs are yet to be solved. The studies presented a comprehensive review of problems related to the development of smart homes with WSN technologies. For WSNs, if the network coverage Exceeds a certain range or the network environment cannot Provide line-of-sight transmission, then high transmission error and data loss rates may occur. Hence, designing a scalable Network infrastructure for WSNs is very important. Although several techniques have been proposed to improve WSN Connectivity, the challenge of improving connectivity In WSNs still exists. Furthermore, WSNs and wlans both operate in the 2.4 GHZ ISM (Industrial, Science and Medical) Band. Experimental results have demonstrated that Wi-Fi networks and WSNs may function together even they Operate in the same frequency band. However, inevitable Wireless interference and packet losses may occur in WSNs. To solve this problem, some methods have been proposed for Interference avoidance or coordinating such a heterogeneous Network environment. However, a more effective Interference immunity solution for WSNs remains to be found. To resolve the issue of wireless interference, the WSN is integrated herein with the PLC (Power Line Communication) Technology to realize a smart home control network.

Block Diagram Explanation :

                    The system controls application through PLCC. In PC you will be providing instruction to control ON and OFF of the application. PLCC, Power Line Carrier Communication, is an approach to utilize the existing power lines for the transmission of information. In today’s world every house and building has properly installed electricity lines. By using the existing AC power lines as a medium to transfer the information, it becomes easy to connect the houses with a high speed network access point without installing new wirings. In the temperature functional module we developed, we use the LM35 series of temperature sensors. The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Fahrenheit temperature light dependent resistor (LDR) is a resistor whose resistance decreases with increasing incident light intensity; in other words, it exhibits photoconductivity photoelectric or light sensing device are used in almost any branch of industry for control, safety, and sound reproduction and inspection and measurement.
