Abstract:With the improvement of people's living standards, smart home has been rapid development, smart home lights are also getting more and more attention。In this paper, we design a MSP430 based on smart home lighting system, the system can be realized according to the surrounding brightness and whether it is automatic switch lights, manual wireless control of the switch, brightness adjustable, and the timing of the open function。The system mainly includes the remote control module and the control module,choose MSP430F139 as the main control chip。The remote control module is mainly composed of a key module, a display module, a wireless transmission module and a main control chip,The button is provided with an opening and closing of the lamp, the timing is open, the timing is closed, and the automatic 5 working states are displayed by  the LCD12864,  and the  NRF24L01 chip  is  transmitted to the     control

drive module；driving module by the human body infrared sensor, optical sensor, voice   control

sensor, wireless transmission module, LED driver module and the main control chip composition。The master module reads the data received by the  wireless transmission  module, and chooses the working state of the lamp；when selected automatically , the system can control

the status of the lamp according to the sensor's data。The system uses the energy-saving chip as the main control chip and the energy saving and environmental protection LED lamp as the lighting facilities, so as to realize the function of intelligent environmental protection integration, according to its system functions and high reliability,it has the promotion value。

Keywords: MCU，Remote control，Automatic，Brightness adjustable
