| Abstract: | A novel smart lighting control strategy is proposed based on the MCU of AT89C52 for saving electrical energy,especially aiming the severe lighting waste in the classroom.During the whole system operation,the light intensity detection circuit will not be generated unless the system has detected the people’s activity via the sensor.The detection signal can be transformed into the digital signal that can be processed directly by ADC0809,and MCU can control the constant LED light automatically by the digital signal.Finally,the purpose of the lighting energy conservation control can be realized. |
