Temperature monitoring and controlling is done with
the help of a microcontroller and LM35DZ is the temperature
sensor. The temperature is displayed on the LCD screen and
the desired value of temperature is also set. The entire
decision making is done with the help of a microcontroller
ATMega328. This type of system can be installed in any
place where we need to maintain temperature approximately
constant. Also, by applying more sensors like light intensity
sensor, barometer, humidity sensor etc, more parameters like
light, atmospheric pressure and humidity etc can be
monitored and controlled which are vital for any industrial
process. The system has various advantages over other
similar systems such as cost-effectiveness, smaller size, ondevice
display, less complexity and greater portability. This
project can be used in industries to measure the temperature
and control the temperature as per requirement. It can be used
in tea factories to continuously monitor and control the
temperature required for processing the tea leaves. It can also
be used in confectioneries for preservation of the sweets. The
system can be used in green houses to control the
temperature for the proper growth of plants. Temperature
monitoring and controlling action can be used in home or
various halls like conference room, seminar hall to control
the temperature of room.
