Traditional
thermostats can only have their temperatures adjusted from one central location.
Also, any temperature adjustments must be made in relation to the temperature in
that one central location, independent of temperatures in other rooms. We plan
to design a portable thermostat with its own digital temperature gauge that can
be operated from any location in a household. The portable unit will read the
temperature at its current location and relay this through a wireless link to
the base thermostat. Adjustments to the HVAC system can also be made from the
portable unit. The base thermostat will read the incoming information and
activate the appropriate HVAC operations (i.e. heat, ac, etc.). The base will be
composed of a personal computer (PC). The PC will connect to a
digital temperature gauge, a wireless device, and a test box. This test box will
have several LED’s showing the current mode of the HVAC system. The PC will
emulate the microcontroller and the user interface of the base thermostat.
