The Design of Intelligent Lighting Controller Based on the SCM

Abstract:

The intelligent lighting controller based on the SCM uses the pyroelectric infrared sensor and sensitive optical sensor to collect the signals, which are sent to the SCM after changed into the digital signals by the A/D converter, and then the SCM controls the lamps on or off according to the signals collected by the pyroelectric infrared sensor and changes the duty cycle of PWM wave according to the signals collected by the sensitive optical sensor to adjust the lighting power of the lamps till the difference of the indoor lighting intensity and the setting point is less than some certain value achieving the constant light intensity intelligent illumination. Actually, compared with other lighting controllers, this controller can not only be able to avoid the waste of resource, but also effectively extend the life of the lamps.
