Designand Implementation Of Wireless LED Lights Control System Based On High-performance Microcontroller

With the development of economic,social,information and networktechnology,the pursuit of convenient,comfortable and high quality life isbecoming more and more intense,home life is moving towards the direction ofintelligent informatization.Intelligent lighting control system as an importantpart of smart home achieves the features such as energy saving,environmentalprotection,intelligent,comfortable by the way of controlling the householdlighting system intelligently.Study object of this project is wireless control system for tricolor LEDlights which is based on high-performance microcontroller.The controller couldautomatically get the brightness of household environment and control theillumination intensity of LED lights:when the household environment isdark,LED lights emit white light; when the household environment isbright,LED lights stop lighting.The controller can not only control the lightingbrightness,but also change the lighting modes such as sleep mode,entertainmentmode,reading mode and so on which can be controlled by intelligentterminal.The intelligent terminal sends workmode commands through Bluetooth to decide the lighting mode.Variable lighting modes greatly enrich and facilitatepeople’s household life.The controller can also be used as hygrothermograph tocollect the temperature and humidity data in the household environment andmonitor the comfort level.During the development process of wireless LEDlights controller,high-performance and low-power consumption microcontrollerMSP430F149is put to use to achieve its basic function firstly,then ARMmicrocontroller Hi3516is used to upgrade the system.
