Intelligent home control system Abstract：This design is used to use simple and complete functions of high performance STC89C52 as the main control chip, and then take the intelligent curtain Home Furnishing system with infrared remote control, photosensitive resistor, relay, stepper motor, and a number of independent key peripheral devices。 As a wireless receiver module, SC2262 plays the role of signal transceiver in this design。 It has been used to connect infrared remote controller and chip。 The relay generates an electric current to drive the stepper motor to rotate vertically, thus indicating the opening and closing of the curtain。 The photosensitive resistor can automatically change the light condition of the environment to realize the automatic switch of the curtain。 The existence of the limit switch also makes the design more safe and can be terminated by emergency operation。 This design can improve the user can in the daily life of the quality of life through the module design of these distinctive and full automatic mode of operation, the infrared remote control mode and automatic light detection mode two modes of flexible use。 This involves the hope that through the initial design of the system for the future more intelligent home system to provide some inspiration。
