LDR senses light intensity and give its corresponding electrical output. This output is inputted into a microcontroller ( 8051 family). Microcontroller processes this input and give output control signals to various components like to motor driver (L293D ic) to drive window curtain, to buzzer for alarm, to light and fan to ON/OFF.
In morning, bedroom fan is switched OFF, outdoor light is switched OFF, window curtain is opened. In evening, bedroom fan is switched ON, outdoor light is switched ON, window curtain is closed. Buzzer is used to alarm whenever there is chance in morning to evening or night to morning.
