 After 5 working days (not consecutive) we had a prototype ready. The first test was made at Eric Cosio's lab at the PUCP in Lima. After 5 working days (not consecutive) we had a prototype ready. The first test was made at Eric Cosio's lab at the PUCP in Lima.

 The prototype consists of a custom-made PCB and housing by Spelsberg which already had the cable gland preinstalled.  The prototype consists of a custom-made PCB and housing by Spelsberg which already had the cable gland preinstalled.

 Unfortunately, there are no measurements yet on power consumption. But we are guessing that the node would hold up for at least one or two years on one battery. Unfortunately, there are no measurements yet on power consumption.

 As a reference: In photo 2 you can see the dendrometer logger that was used before. It was quite big and heavy and the main disadvantage is that the battery lasted only 2 to 3 months. Especially in remote locations, this is really hard to justify. The only advantage it currently has is that multiple dendrometers could be attached. But once the new LoRaWAN node proves itself in the field, a slightly bigger version could be developed which could accommodate multiple dendrometers if needed. As a reference: In photo 2 you can see the dendrometer logger that was used before.

 +There was only one f the old loggers installed at the Tambopata tower location. This got replaced by one of the new LoRaWAN nodes.
