Have a look at<a href="https://www.youtube.com/channel/UCv85CXnZUXEKnlZpQapTAwQ/videos" target="_blank"> The Things Conference youtube channel</a>. They're still uploading the keynotes from the last conference but some highlights you can now get daily satellite uplink for ~$30/month, AWS IoT services integrate with TheThingsNetwork stack for device management, and there are just too many urban environmental sensor companies using LoRa to name now (target is usually office buildings/hotels/etc). Big names like Microchip and STM offer factory deployed encryption solutions, or at the hacker end there are a dozen Pi/Arduino/similar kits.

EnviroSensors and LoRa experts, would some of you like to address Zach’s questions below? This topic aligns well with discussions in our last call & ESIP Winter Meeting re: the trade-offs between instrumentation with a low entry price point vs. more expensive
solutions (e.g., Campbell) that generally have less problems and require less maintenance over the long-term (my preference/bias).

<p class="MsoNormal">I’m in the process of setting up a network of environmental monitoring equipment and climate manipulations in the Australian Alps as part of the Australian Mountain Research Facility (<a href="http://AMRF.org.au" target="_blank">AMRF.org.au</a>).
We’re a team of ecologists and natural resource managers interested in knowing how alpine grasslands will be affected by climate change, fire, etc. As part of our remote monitoring, we’ll have soil moisture and temperature sensors distributed throughout many
1-hectare plots, each with 4G comms, logger and other sensors. These sites have wild temperatures, precipitation, etc. I have recently discovered LoRa as an inexpensive option for such sensor arrays compared to Campbell or other brands that focus on durable,
hardwired options. I’m curious to know what stories you field ecologists have regarding use of LoRa probes in rugged field conditions for multi-year deployments. Here is one such example
<a href="https://www.tindie.com/products/tinovi/lorawan-soil-moisture-temperature-ec-sensor/" target="_blank">
https://www.tindie.com/products/tinovi/lorawan-soil-moisture-temperature-ec-sensor/</a> My instincts tell me to go for the tried and true hardwired options despite the high cost. But I recognise that with LoRa instead of hardwired probes, the project could
either put out HEAPS of sensors out or alternatively save a fortune. Thoughts? Is LoRa a few years off of having high-quality, durable options that can withstand the elements for years on end? I would appreciate your stories.<u></u><u></u></p>
