碩士 === 國立屏東科技大學 === 生物機電工程系所 === 106 === This study proposes a wireless sensor network (WSN) system for agricultural application. Multiple sensors are integrated and compromised in the system, which collects several types of environmental data, such as temperature, humidity, atmosphere pressure, intensity of carbon dioxide, and light quantum intensity. In this study, sets of wireless transmitting modules are tested and verified to be implemented in the system. Nodes, defined as an intersection combining sensor and actuator, are set up in an actual greenhouse for test. A highly efficient and energy-saving data structure is built, using Cyclic Redundancy Check, CRC, to avoid receiving error data. Hence, a tiny database table structure is established for user to do a rapid search and also reduce storage space consumption. The calibration method is used to measure the unstable light quantum data due to sampling process in the analog-to-digital stage. A website is designed and used as a user-monitoring platform. The user can setup a time interval from the homepage on the website. After that, the historic environment data curve is shown in the homepage with a user set time interval.
