Hello,
First post here 🙂
I’m going to deploy two solar powered mini ultra pro nodes with LoRa radios in Denmark. The climate can be quite harsh, with temperatures typically ranging from -10 in the winter to 25-30 degrees C in the summer. We get a lot of rain and although it can be arid in shorter periods, conditions are generally wet.
My primary challenges as I see them are:
- Protecting the electronics while still exposing the sensors (temp, humidity, pressure). I’m considering using an electronics potting compound here + waterproof enclosure.
- Insulating the battery in a way that makes it not overheat in the summer and keep it on or above 0 C in the winter
- Weatherproofing the antenna connection without obstructing the signal
There’s plenty of resources on this on the big ‘ol web but I have yet to stumble upon a very good one. Suggestions, experience links and tips are all very welcome. Thanks!

I would definitely suggest using some sealant/epoxy to tighten everything up on holes that you drill on the enclosure.
And it’s best to orient the holes facing downwards although you might have already seal them.
The amount of heat that we get here in tropical area is crazy close to 50 Degree Celsius inside the enclosure based on our past experience. 25-30 Degree Celsius is really a very accommodating range. Below 0 Degree Celsius, I doubt that the Li-Ion would charge effectively although it can still be used to power still down to -20 Degree Celsius.Also if possible, do add some desiccant packs, it really helps.
