ABSTRACT
Despite the recent economic crisis, energy efficiency remains a
priority for developed nations. Compact cars and hybrids are
replacing larger, gas-guzzling vehicles. Efficient, fluorescent
lamps are replacing less efficient incandescent ones. However,
few options exist for efficient temperature control in existing
homes. Our proposal, Automated Climate Control (AC2), fills this
gap by providing energy-efficient temperature control for existing
homes.
To improve the efficiency of existing heating and cooling
systems, AC2 accurately measures temperature and automates
temperature regulation. AC2 uses a wireless sensor network to
retrofit existing systems. Temperature sensors are used to measure
temperature on a finer granularity than a centrally located
thermostat. A servomotor controlled by a wireless mote
automatically opens and closes the vents based on ambient
