The nodes (or sensors) in the park are shown above. We also collect battery voltage levels and signal strength data. The data can be graphed from the above page.

Above is a screen grab of part of the the project back end, which as you can see is excellently simple. The sensor data from the park is uploaded automatically to the server and another page uses Javascript to do Ajax call backs to the server. This access and structure was built by Adrian Soundy.
