So interesting! I’d always wondered about the history behind this. After your hint, there’s more info here: https://www.cardinalpeak.com/why-do-cds-use-a-sampling-rate-...

Appreciated this — thank you!

This is a super interesting tip — thank you, we were not aware of this (it is reminiscent of tracking of shipping vessels). Do you know of where and how we might be able to make these data available to local partners, like the Tembé tribe, and others? Do you have any contacts at Deere Forestry? Thanks in advance.
Great question, and one that’s of particular importance in our design. Many IoT-type systems make use of on-device data analysis in order to minimize the most energy intensive process: data transfer. Our hardware focuses instead on getting full audio streams up into the cloud in near-real time, continuously, 24 hrs a day. This requires an exceptional amount of energy, as well as the ability to pool energy to continue operating at night and during poor weather. That said, we’ve really overcompensated on energy capture and storage—we operate under the assumption that we should be able to support 1.5 watts of continuous power draw 24hrs a day (normally it’s closer to 50% of this). But that means we try to be able to generate 35-40 watt-hours of solar energy for each day (on average). This is further complicated by the shady/infrequently lit conditions of the tree canopy. So, when direct light shows up (sometimes for moments or minutes only) we want to be able today capture as much as possible (high charging amperage and ample solar panels). Our batteries (LiFePO4) must be able to support this, and not decline over 1-2 years of use being fully discharged and recharged each day). We also designed a type of solar array that is specifically intended for the tree canopies. If this is interesting I’d be more than happy to elaborate more!
TechCrunch just posted a slightly broader article on the project: https://techcrunch.com/2018/03/23/rainforest-connection-enli...
It works pretty well, as demonstrated here in an event within the last couple of weeks in Peru: https://twitter.com/lilitjejauregui/status/97585519352188518...
Thanks for checking out Rainforest Connection! Seems that there are lots of [appropriate] questions about how well this works in the forest, and how our partners on the ground follow up on alerts. Here’s a recent intervention in Peru that sums up the process: https://twitter.com/lilitjejauregui/status/97585519352188518...
It's for carbon capture and storage, as a mechanism for slowing climate change.

An even more powerful and touching video clip of this frog, as captured by Joel Sartore in his Photo Ark project, can be found in this video (starting around 6:00): https://www.youtube.com/watch?v=49lzBOB4HB4
