Question

Design of an intelligent and effective light control system:

Answer 1

hy here is the answer.....

• The PIR sensor is used to detect whether any occupants are there in that room and LDR is used to detect the intensity of light in that room. Apart from this an algorithm can be implemented in our system which uses both the LDR and PIR sensor to decide whether to switch on the light or not.

This proposed system will able toprovide the needed light which provides the satisfaction of users and will provide energy saving and management...In this paper the Lighting Control System and the decision making algorithm, are discussed...
