Testing in the OPEnS lab with our tree (Cassandra)

This is an actual datalogger in the field
Testing our buck regulator prototype
Some of our early probe prototypes failed inside the tree due to excessive heat. The black spots are where the heater resistor was soldered.
Flex PCBs and smart probe PCBs during the soldering process
Testing the smart probe
Field testing at Lewis Brown Horticulture Farm
