After building it in the lab over the winter, and indoor testing, we deploy the soil moisture geosensor networks for field testing outdoors today.
Soil moisture geosensor network in weatherproof containers
Sensor setup in weatherproof box
Field testing of wireless soil moisture sensor network
Installing the solar panel to power the node and sensors
Node 1: transition between full sun and full shade
Node 2: mostly shade (but enough sun for solar panel)
Node 3: South location, full sun
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.
Next step: blueberry barren
