We're pleased to announce that on June 15 we deployed a series of both weather station and burrow sensor nodes on Great Duck Island, ME in the second year of this project. This project serves to monitor the Leach's Storm Petrel on Great Duck Island in collaboration with UC Berkeley, the Intel Research Lab at Berkeley, and the College of the Atlantic. We have a single hop network operating for 5 weeks now. On July 15th, we deployed a multihop network based on maximum reliable path routing from Alec Woo operating. We anticipate adding more nodes to the network in the next week to monitor increasingly more petrel activity. The multihop network traverses through a dense forest of highly active petrel nesting burrows approximately 1/5 of a mile long. We expect that the network will run for over 2 months (well into September) on an 850mAh LiSO2 battery (only 34% of the capacity of two AA batteries). The deployment features mica2dot nodes sensing humidity, pressure, temperature, infrared radiation, total solar radiation, and photosynthetically active radiation. The burrow motes are tiny in size: 1.25" in diameter and 1" tall. We designed the hardware, software, and enclosures from scratch using the application of monitoring seabirds as our primary motivation.
We have redesigned the website to make it easier to view and analyze data from the deployment. Sensor data can be plotted, and the main page displays the averages of the climate currently on the island. Data streams into the database every 15 minutes via satellite such that it is possible to view the most current readings from GDI. I encourage everyone to check out: http://www.greatduckisland.net All of the mote software was implemented in TinyOS with nesC and is checked into Sourceforge at tinyos/apps/TestLabApp/. More information about the deployments can be found on the website. The biological context and previous deployment information can be found in these papers: http://www.cs.berkeley.edu/~polastre/papers/wsna02.pdf http://www.cs.berkeley.edu/~polastre/papers/masters.pdf (see the "System Evolution" chapter for information about this year's motes, enclosures, and diagrams) If you have any questions or encounter any problems, please let us know! We're open to feedback, criticism, comments, and queries. -Joe _______________________________________________ Tinyos-users mailing list [EMAIL PROTECTED] http://mail.Millennium.Berkeley.EDU/mailman/listinfo/tinyos-users
