Abstract:
This paper is design of PIC-based room
temperature control system using ventilation fans.
This design is provided with a switch for
determining whether the room temperature is
increased or decreased. This control system can be
used to adjust the temperature of the room
automatically by using a few ventilation fans on it.
PIC microcontroller is the main control unit. There
are two temperature sensors in this device, one for
indoor temperature detection and the other for
outdoor temperature detection. In two different
places, two fresh air fans are placed in the room
and their fan circulations are designed as output
parameters. Both of these fans have the same goal.
It is to lower the high temperature as soon as
possible. The temperature values are displayed on
six 7-segment LEDs. The controller can be used in
two different ways: UP mode to reduce temperature
and DOWN mode to turn up temperature. This
temperature control system can be used in small
area such as home, office, mini market, etc.
