Next week we will be assembling and deploying four new dendrometers at the Black Rock Forest Consortium Summer Science Camp. A number of middle schoolers will be able to see what goes into constructing and installing the dendrometers and get a chance to answer some questions about how our trees change from day to day.
On the Technical Side
It seems that wet foliage and understory can contribute to signal loss when the signal is weak to begin with. At the research and development network at the Lamont Doherty site we experienced signal loss after rain. After repositioning the logging unit in a window we experienced much improved results. We also changed radio frequency settings to avoid interference from nearby wifi.
Battery life is at 5 days using a 4,000 mAh battery. In development is expanding the reporting period to improve battery life.
