Okay , thanks. back to my subject. I am playing with the thermal camera AMG8833. The simple sketch produces an array of 64 (8*8) datapoints. It was my idea to calculate an average and send that with a node, but I am not an arduino expert. Has anybody made already such a sketch to send data to a TTN gateway?
maybe its an idea to open a separate topic for that ?
I have seen the libs, think you need a bit of 'local processing ‘power’
This Walabot Starter version uses a three-antenna array to illuminate the area in front of it and sense the returning signals. The signals are produced and recorded by a VYYR2401 A3 System-on-Chip integrated circuit. They are then communicated to a host device (like your phone or computer) using a USB interface, which is implemented using a Cypress controller.
Soil sensor. Since a couple of weeks i work with the Soilwatch10 ( 3V) in combination with the Dragino mini dev. I made calibration ( With the WET sensor) for the volume soil moisture.
I did the search for you 
maybe you want to write a story how to use and what your experiences are ?
I made bad experience with such a moisture sensor from Tindie.
The weak points of these are, that the SMALL side of the board is not sealed and it gets whet under the lackage and it blisters off (in my case after some month!)
Very sad, that the seller take no notice of the problem, nor action to replace it.
So you have to seal it with “tropenlack” to make shure it’s prepared for a long life.

good results with this kind of sensor right now
Those small soil sensors are pretty poor and only an indication that the soil is wet or dry and wont last very long. To do any serious long term soil moisture monitoring at any depth then you’d need to look at professional sensors from Irrometer, Sentek and others.
They may not be budget sensors, but you get what you pay for,

Hello
At this moment i found this :
PiGI goes TTN - IoT Radiation Monitoring
At this point, 12 PiGI - Raspberry Pi Geiger-Müller Interface nodes are in active deployment at TDRM, helping to monitor the environment independently and so far reliably. Additional 12 nodes are on the current roadmap. That is a great success story and just in the spirit of the idea, development and open-source model of it.
Now the TDRM Working Group at Karel-de-Grote Hogeschool, Campus Hoboken in Antwerp pushed it even further and developed a LoRaWan based TTN (The Things Network) Adapter for the PiGI, to have it connected to the Internet of Things.

Soil moisture and soil humidity are different things. You will see almost no response in soil humidity until the soil moisture becomes very dry.
