The Make: Nature workshop at this summer’s Black Rock Forest Summer Science Camp was a success! Twelve awesome kids got a chance to learn to how to solder and the basics of circuitry. They used those skills to construct and deploy their electronic, wireless point dendrometers on four red maples near the science center. Looking at the data collected with their devices, the kids got to compare their hypothesis of tree stem shrinkage and swelling from water use against actual dendrometer data. Be sure to head over to the data collection site to check out the charts!
On the Technical Side
There seems to be a bit of variability on battery longevity. The last charge at the Lamont installation lasted over 6 days. This would indicate a variation in current usage by the reporting unit, perhaps related to heat.
