| Summary: | 碩士 === 國立交通大學 === 電機學院電子與光電學程 === 103 === In recent years, smart phone, personal computer (PC) and smart television (TV) are becoming more and more popular owing to the continuous reduction in price and the improvement in performance. Besides, using smart phones and PCs for the Internet access, as well as the interconnection among these electronic devices are highly desirable. The interconnection among these electronic devices is also known as Internet of Things (IOT). Using wireless communications for the IOT allows users to access and share information easily and conveniently.
In this these, we will design and develop two wireless communication systems for the IOT. In the first system, an optical wireless communication link using infrared (IR) is constructed. This includes the development of an Android mobile phone application (App) program which can convert the signal into sound-wave file. The sound-wave file is then used to drive a self-developed IR module to control the TV. In the second system, the App program can also be used to control and trigger a MCU OT8000 module, which is connected to a PC via universal serial bus (USB) port. After the initial hand-shaking of the mobile phone and the MCU OT8000 module, the screen and the control functions of the mobile phone can be projected to the PC using WIFI technology. Hence, the mobile phone can be controlled using the keyboard and mouse of the PC.
