Abstract
In the current study, we developed a wireless sensor network system to support the coral ecological system survey activities for conserving the coral reef environment. This paper studies the required functions of a data browsing system to confirm information of underwater environmental conditions gathered by sensor network. Sensor information acquired by each sensor node is transmitted to and gathered in the base station. The base station serves as the Web server. The users such as coral researchers can access monitoring information by using a Web browser. The web page displays monitored information that was gathered by sensor nodes. The Web page can display the temperature and image information of a period required by the user. Each sensor node condition can be checked by selecting the sensor node.
