To collect environmental data in forest, nowadays, the forest ranger would carry numbers of devices to collect the environmental status and write down the position where they collected, such as camera, GPS, then write all of the data down on the paper. This method can make some errors due to a lot of data and take time to finish. If there is a sensitive data or and important situation which should be solved in a short time, this method cannot solve the problem. This project, using wireless sensor network, set up the station which automatically collect data, and then using android tablet to immediately collect data from the station, so that they can handle the important situation in time. After that, they can easily export the collected data to the central server.
