Efficient Power Manager Based on people Visitor counting System
Electricity is one of
the most important requirement of modern civilization and the demand of power is increasing
continuously, with already installed power generation system the cost of this
is also high and , we cannot replace the new generating system every time .to
solve this problem we need to manage energy efficient lightings at home
Hence we provide
efficient power manager based on people visitor count. In this system gives
powerful and efficient solution for energy efficient lighting to save energy by
optimizing home appliances based on a person’s presence in the
room using different wireless technologies like IR sensors. When
a person enters in room and leaves out of his room depends on this system will
decided switch the home appliances like room lights on.
Block diagram:
This system possesses
two sets of IR transmitter and IR receiver to detect the persons entering and
leaving the room. The IR transmitter continuously emits IR rays generated by
the timer circuit at some specific frequency. This frequency is detected by the
IR receiver that gives input signals to the8051 microcontroller.
The microcontroller is programmed in such a way
that for every pulse that enters the IR sensor, the system also counts the
number of persons entering and leaving the room it increments the counter, and
for the exit sensor signal, it decrements the count. And displays that
information on 7 segment display. After receiving the pulse signal from the IR
sensor, the microcontroller switches loads by using relay. When nobody is there
in home and count is zero the microcontroller will switch off the appliances to
save energy.
