IMPLEMENTATION OF WIRELESS SENSOR NETWORK FOR ENERGY CONSUMPTION MONITORING AND CONTROL IN SMART HOME

The increasing demands for electric power in daily life with the consuming power increasing day by day. The energy optimization that used in homes has grown importance in the era of smart technology. This will force us for a goal is to design and implement a wireless sensor network (WSN) for real-time consume energy monitoring and controlling in smart homes and save electric power that leads to sustainable energy by reduce the power consuming in electric device and to afford homeowners precise control over how much energy can be using, lower total consumption, and support in the creation of smarter, greener residential environments. the task of proposed system is to influencing the technology of advanced sensor and effective communication protocols so that electric power can be conserved throughout the deactivation of devices that are not in use. The methods used are: creating a systematic architecture for the wireless sensor network that is suitable for monitoring and controlling smart home energy consumption and indicating the accurate sensors for detecting various parameters. The system model consists of (microcontroller (UNO R3), temperature and humidity sensor (DHT22), electric device (fan) and Xbee as wireless communication module). The system saved the power throughout turn OFF Fan if the temperature of room below than 26 C° and turns ON if its exceeds or equal 26 C°. These events are monitoring and control by using internet of things (IoT). The system has two location area End Node and Base Station; the data sent from End Node to Base Station by Xbee modules in real time. The following results were obtained: the power in KWh has been calculated and it’s recorded about 1.43 kwh in one day and 42.9 kwh in 30 days (in April) and the cost reach 815.9 Iraqi dinar. Conclusions. If the model didn’t used the fan is in ON state in all days therefore the power reach 2.64 kwh in one day and 79.2 kwh in one month and the cost recorded 1504.8 Iraqi dinar. This paper emphasizes how WSNs can transform smart home energy usage monitoring and control. The usefulness of the arrangement and the encouraging results give prominence to how vital WSN technology is to improving sustainability and energy efficiency in residential settings.
