After building it in the lab over the winter, and indoor testing, we deploy the soil moisture geosensor networks for field testing outdoors today.

Sensor setup in weatherproof box

GSN_Umaine_sensor_install

Field testing of wireless soil moisture sensor network

GSN_Umaine_sensor_install2

Installing the solar panel to power the node and sensors

GSN_Umaine_sensor_2

Node 1: transition between full sun and full shade

GSN_Umaine_sensor_3

Node 2: mostly shade (but enough sun for solar panel)

GSN_Umaine_sensor_1

Node 3: South location, full sun

GSN_Umaine_basestationLR

Raspberry Pi base station using Xbee to sensor nodes, and internet to upload data to a database.

Note, that node 4 (with sensors 400, 401, 402) is in the lab. Nodes update every 6 minutes.
