Weather and Land Recording Device
Adaptable Community Environmental / Wildlife Assessment Mesh Network
2009 – Present (ongoing)
The sensor network is a mesh network design for environmental monitoring. The network can consist of a large number of nodes or as few as one unit on its own. As of 2011, there are two developed versions of the nodes, a unit that is meant to be stationary, running autonomously on solar and/or wind power, and a mobile version. Each node is powered by a rechargeable battery, providing ample usage time between charges in moderate temperatures. The unit’s basic capabilities are listed in the table below, and additional sensor input is available through simple customization.
The software and hardware are all open source and are highly customizable to suit the needs of the community, individual hunter, or researcher. Currently the data is recorded as a string of comma separated values, to be easily imported into a variety of analysis software. The data can also be accessed in real time, allowing for additional real-time situational awareness.
An example of its usage might be that a hunter would ‘check-out’ a node, and head out on the land to hunt. Along the way a set of environmental measurements would be logged automatically and stored according to their location. The hunter could also use the buttons to record locations that they wish. Upon returning, the node would automatically upload its data to a central server. The data would then slowly aggregate, building a database of land use and measurements of microclimates along the way. Under this paradigm of ‘citizen-sensing’ the community owns its own science and allows for healthy, sustainable monitoring of their local environment, rather than relying on southern researchers. Another possible program for its use could be the comparison of weather data and traditional knowledge by an elder, learning to read the sensors while using their own knowledge of the land and wind to make their predictions more accurate.
The Tatsipaaq extends the connection to the land through technology for the entire community. The nodes can also be distributed on the land in fixed locations and can operate continuously, sending environmental data back to the community in real time as well as serving as repeater stations extending the reach of the network. A database of environmental data would be built by the community, for the community rather than needing to rely on ‘southern’ research.
