During the duration of this project researchers refurbished the electronics of all 32 dendrometers and manufactured carbon fiber parts for the new 3 spring design. Two deployments were completed, one at the beginning of the summer and one in mid- summer.
The deployment in mid-summer included 3 devices with a new 3-spring design to improve stability over the original 1-spring design from previous years. Researchers worked closely with engineers to implement a data-cleaning algorithm, which removes statistically significant outliers and removes skipping or incongruencies in the data due to bumping or other mechanical disturbances. While effective it is still being improved, live updates are transmitted via 4G LoRa telemetry once every four hours. Measurement data is stored on the SD card at the original 15-minute interval. To further investigate the dendrometer and the 3-spring design, researchers performed off-season experiments in a greenhouse. Researchers continued to develop 4G telemetry capabilities for rapid evaluation of plant water status and device functionality.
