Building Automation Using Wireless Sensor Networks

Abstract

The use of wireless senor networks in building automation is gaining popularity so as to improve the safety, security, and energy efficiency of the buildings. The automation solution will differ as per the type of building. In this paper, authors have proposed three wireless sensor network (WSN) based automation solutions for buildings of different sizes. First strategy has been proposed for a small building using a single network. Second one is for a large building complex using multiple networks and third strategy is for building automation solution for local individual control. For building automation both monitoring and control of the parameters of interest are required. Authors have implemented first strategy in a small room of 501.9 m length and 410.9 m breadth. The humidity temperature and pressure (HTP) and TL sensor nodes of Eigen Technologies Ltd. have been used in this research work. HTP sensor node has been used for monitoring of humidity, temperature, and pressure. However, for the monitoring of luminosity TL sensor node has been chosen. Four sensor nodes of each type have been placed at appropriate locations in the selected room. Finally, a general control strategy for the temperature control has been proposed for the control of the building automation of a small building.
