Abstract：This paper designs an infrared remote intelligent LED controller based on Atmega 2560,which was integrated with a human body infrared sensor,a temperature and humidity sensor,a light sensor and a clock chip.It has three PWM control circuits to adjust the color temperature and brightness,as well as the color if the light permits.The integrated sensors have their own switches to control: when human body infrared sensor is enabled,the lights can be switched automatically following people ' s activities;when the light sensor is enabled,the brightness is adjusted according to the outside lightness.When temperature and humidity sensor is enabled,the current temperature and humidity outside can be displayed on the LCD screen.The color temperature may go with the current temperature.The buzzer rings when the current temperature and humidity outside is beyond the normal range.The controller can be operated with infrared remote control as well as metope button.It is an energy conservation and environmental protection system with quite a market value.
