Overview and latest status
Readings are taken every 20mins and stored on nodes. At 30mins past each hour the border router PC fetches the readings and deletes them from nodes. It then POSTs them to our database in Southampton.

summary of temperature data obtained from inside the node cases as received by march 2016. The number of nodes offline and saving their data to their store increased during winter.
adc1 is the moisture sensor raw data. Here the upper trace is from the Hummock node which is very vegetated, whereas the lower trace is from router3 in the peat zone – which is much wetter
