Internet of Things based smart home system design through wireless sensor/actuator networks

摘要

This paper describes the design and implementation of a wireless home automation system that can be used for general purposes in our life. The proposed system is designed for easy installation, so it could be use at any location to gather indoor conditions. The proposed system comprises of a wireless sensor and actuator network which is low cost and low power. Each wireless sensor node senses and transmits the variations in the local temperature, humidity and luminosity to the cloud database. The cloud server receives the data and stores it in the table and plotting the variations simultaneously. The user web interface provides graphical data analysis. The Web of low-power wireless home energy management system allows the temperature, humidity and luminosity variations to be viewed and controlled whenever user want from anywhere in the world. Also, when the large variations in temperature, humidity and luminosity value occur, system will run actuators like heater, cooler, ventilation fan and lighting equipments. It is expected that the proposed system will be more useful in our existing home because of not necessary wire connection and massive energy saving potential.
