  This work presents the design and implementation of a wireless home
monitoring and automation system consisting of wireless sensor/actuator nodes,
wireless camera, and a home server. The low-cost wireless sensor/actuator node
features temperature, light intensity and motion sensors, and actuator driver
circuits for the control of motors, heaters, and lights. Server and client
programs used to monitor and control the home were also developed. The home
server receives and processes sensor readings, such as temperature and light
intensity readings, and also transmits user commands to wireless nodes. The
system provides ambient condition monitoring, graphing of sensor data,
intrusion detection, automated device control, and video monitoring in order to
achieve improved security and comfort in the home. In addition, users have the
flexibility of determining sensor-actuator interaction at run-time. The
developed system could also put the home in various configurable modes based on
user requests, time or environmental cues.
