1. DESIGN OF SENSOR MODULES OF ACTIVE & INTELLIGENT
ENERGY-SAVING SYSTEM
Introduction:
With limited territory, large population, and rare natural resource, all nation
mostly depended on import to provide civilian needs up-to 97%. Nowadays, the world faced
successive progress of domestic industries, daily increasing energy demand, international oil
price unstable, summer electricity consumption limitation, and solving more and more serious
global green-house problem. To solve the energy shortage and green-house problem, all nations
reach to the common sense that is to positively promote energy-saving activity. Hence, Energy
Bureau of Economy Ministry actively impetus relative energy-saving strategies according to
conclusion of Taiwan Energy Conference, and hope to save 6580 thousands Kilo-liter oil till
2010, furthermore up-to 24000 thousands Kilo-liter oil till 2020, and especially established
“Energy-saving Measures for Offices of Government” and giving orders to official units to
promote relative energy-saving activities, all that hopes to lead civilian or industrial
organizations to follow the pace and enhances the display of energy-saving education to come to
the goal of saving energy and increase the competition strength of whole nation .
Existing System:
There are lots and lots of technique had been emerged to save energy. But nothing is
more effective to be implemented in the real time life. The cost of their implementation is also
high and also there is no automation in the energy saving architecture. To ensure to get the full
energy saving architecture we are going for proposed system.

2. Proposed System:
This paper has proposed an automatic Energy Saving Architecture using solar power. We
would first calculate the area of a space and decide the maximum number of people , after then
we detected the real people number and the luminance parameters and sent back to servocomputer and middle-way to feedback control how many lights in the space should be turn off
and the luminance still meet with the regular luminance 550Lux, the decisive procedure could be
in two ways, one is calculated the factor which was maximum entered people divided by entered
People, and used this factor to multiply the total lights number, so we got the desired turned on
lights, and then we used the detected light luminance to decide whether the luminance was
enough or not, and then feedback control the lights according the judge of intelligent agent
system built in servo-computer. We could directly and dynamically decide the lights turned on or
off according to the luminance sensor signals. If the temperature exceeds due to the presence of
more people Cooling Fan is also switched ON. Power is also monitored and warned through
Bluetooth.
