    LDR Based Automatic Lamp Illumination Controller With High Power/Intensity LED Lighting


    Abstract

    This project is developed for the users to change the intensity of a high power LED light system using PWM technique. It consists of three modules. They are Light sensor (LDR sensor), Microcontroller and High power LED light. The sensor senses the availability of light. When the intensity of the light decreases(night), the sensor sends signal to the driver transistor. The driver transistor sends signal to the ADC of the microcontroller. When the intensity of light increases or decreases, accordingly the sensor sends no signal to the microcontroller. The microcontroller generates corresponding PWM pulses. The PWM Pulse is given to the LED light through driver section. Thus the intensity of light will be automatically increased or decreased according to the room light.
