David Liu and Adam Schrems show off their work at the Fall 2006 College of
Engineering Design Exposition. During this one-day event at the Duderstadt
Center, held December 7, 2006, students from several disciplines showcased
more than 40 projects. Liu and Schrems, both undergraduate students in
Computer Engineering, are displaying their senior-level project, SensorNet,
a system to wirelessly monitor and control a home. Not shown are team
members Eric Moore and Neil Pankey.
With this system, a variety of wireless sensors and
actuators would be installed in a person’s home to provide this service.
Sensors monitor temperature, motion, doors, cabinets, and a variety of other
things. Actuators control lighting, heating, cooling as well as other home
devices. All sensor and control modules communicate wirelessly with a base
station to maintain a current state of the home. A wireless handheld device
is used to monitor and control the home while inside the wireless network.
The base station also serves as a web server to provide remote access from
any web browser.
The initial motivation for this system was to monitor
the home and actions of an elderly person. Installing SensorNet would ease
the mind of worried family members at a fraction of the cost of a nursing
home. In conjunction with some basic artificial intelligence, these sensors
could be used to monitor everyday actions. For example, if a cabinet
containing pills was opened and the water faucet was turned on, it could be
conjectured that the person had taken their medication.
Another use of SensorNet is monitoring and controlling
a home. SensorNet allows household heating, cooling and lighting to be
monitored and controlled remotely. For example, you can turn up the heat in
your home from work so that it is comfortable when you arrive home.
Liu said he appreciated the opportunity to present the
team’s work at the Design Exposition, and he hopes others will take
advantage the course, Advanced Embedded Systems. Also presenting
projects at the Design Exposition were team members Andrew Cramer,
David Masselink, Jacob McCrary, and Jeffrey Rogers, who displayed their
Solar Car Micro-Controller System, and Pritpaul Mahal, Douglas Li, and David
Miller, who displayed their iBrick MP3 Player.
