This article mentions about integrating an intelligent light sensor to the luminaries to save energy during day light because the with day light, the light bulbs can be dimmed and the power can be saved. Actually here one important thing is our eyes can function properly with day light condition provided we have windows with plain glasses in the east and west directions and no lights required.But for many places the rooms are air conditioned ,windows are curtained for privacy reasons and never a day light falls into the place.There fore i feel that these sensors are of no use. If at all a simple light sensor to switch on or off by measuring a set ambient light level
may be help full for those places with large windows and with no privacy requirements. This sensor can work during rainy,cloudy days to switch on the lights.
