| Summary: | 碩士 === 義守大學 === 電子工程學系 === 105 === According to the development of the IoT nowadays, by the technological breakthroughs, the requirement and the function of these connected devices will exponentially explode in the last few years. However, the techniques in the present are not proper to be applied to develop the productions at a low cost and the remote control. The purpose of this thesis is to build a remote control platform system which includes the Km level transmission distance, a low power dissipation, a low cost, many kinds of interface for communication hardware and connection of cloud platform. As a safe design, it prevents the network being disconnected by using the Tree-Star network structure. Therefore, those detects of the techniques in the present can be improved well.
In this thesis, Arduino IDE is used to develop the system, by using the Arduino Nano, LinkIt™ ONE microcontroller board, SX1278 chip, BMP180 barometric pressure sensor, DHT11 temperature and humidity sensor and the photoresistor. The Master is programmed to request, and then read the data of sensor which is sent in different ways from the uniquely addressed Slave. Then the data will be uploaded to the cloud on the Internet. Once the message is received, it can be viewed in the users’ computer or the cell phone monitor window. If any Slave is broken, it will show the details and data on the interface for the convenience to check, fix, debug or build.
