Octobre 16 Deployment, adding sensors

Our first external temperature+humidity sensors are alive!

Until now, the temperature was measured using the board’s internal temperature sensors. And while those temperature sensors are well calibrated, the measurements were not exploitable as the motes are located into water-tight boxes above the orchard, which tend to “heat up” when in the sun.

The Mendoza team went to the Junin deployment site and installed external sensors to report temperature at different heights. Having that information is really important for our research as we know that the temperature can vary to a couple of degrees between the ground and the top of the trees. This temperature difference can make a difference in the occurrence or not of a frost event.

Five motes are now equipped with 4 SHT-31D Adafruit board measuring air temperature and relative humidity, every meter from groud level to 3 m altitude.
