In auditoriums, the lights and fans will be switched on before the show so that there will be no disturbance to the audience while the program is going on. But sometimes due to the weather conditions, we need to operate them in between the show. This may create inconvenience to the audience while the operators move here and there to operate the lights or fans. And even the wires associated to these lights and fans will be running on the floors and in the dark, the audience may feel inconvenience while walking out or coming inside the auditorium as they slip down. To avoid all these problems, we have designed a project that completely eliminates cable wires and the operators to operate the lights and fans in the auditorium.
The
project AUDITORIUM CONTROLLING SYSTEM is an exclusive project that works on
wireless concept, IR. IR remote acts as the transmitter in this project. When a
button is pressed in the remote, the signal will be passed and received by the
IR receiver TSOP Receiver. This signal is sent to the microcontroller which
decodes the signal and performs the corresponding action in accordance with the
button pressed in the remote.
This
IR receiver will be fixed at all the fans and lights in the auditorium. The
output from each receiver is given to the controller. Thus the operator sits at
one place in the auditorium having the IR remote in his hand. Whenever any
light or fan has to be controlled, he just presses the button associated to
that particular load in the remote. The IR receiver receives this signal and
the output is fed to the microcontroller. Now, it is the job of the controller
to receive the signal from the receiver and perform the necessary action.
