’ I plan to use a setup to monitor the internal temperature of oyster and mussel biomimics (the node will be above water). I plan to use about 20 Adafruit Feather M0 RFM95 nodes each with approximately 15 DS18B20 sensors embedded in shells. So far I have managed to get a node to talk to TTN using an…

Dear Daniel, thanks for your interest in our system. All of our code is on GitHub at [1]. As you might specifically be looking for the Arduino sources, [2] might be the right place to go to. [3] and [4] are the most advanced firmware variants we are keeping around there. Reading from DS18B20 senso…

Daniel I opend this Q+A topic for you. Conflict between RFM95W/LMIC and DS18B20 temperature you can use search on this board maybe you can explain a bit more about this project, what is the final objective, the duration of the measurements, the interval the samples are transmitted, the distance t…

Thank you @amotl for the GitHub links. I will take a look. Thank you @BoRRoZ for starting this thread. In short : I am part of a team interested in using biomimics to monitor the internal temperature experienced by salt marsh mollusks at the Sapelo Long Term Ecological Research (LTER) site in Geor…

Hi there, All other problems like proper SPI configuration or appropriate TTN-Cayenne en-/decoding aside, but specifically regarding a possible [image] Conflict between RFM95W/LMIC and DS18B20 temperature timing problem when reading from sensors while there’s something running side-by-side l…

Dear Daniel, thanks for sharing such detailed information about your project. Good luck with everything! Referring to all topics would require a really extensive answer, so I would like to pick just two things out of the topics you are listing which might help you and your colleagues. Power [i…

[image] BoRRoZ: which one do you want to use, the left one should be waterproof (really?), the other you need to make a sensor yourself for under water. The ones on the left work just fine in saltwater conditions (at least for a 4 month deployment), but I have never come across ones that use …

[image] amotl: Please let us know if some of the things we are working on will spark your interest. Thanks so much. I may well take you up on that offer as I work through this project. Cheers!

I modified the adafruit ttn_otaa_feather_us915_dh22 code. I used pin 10 as they use it in their sketch. I am guessing that the issues that @jdelaet and @galagaking mention are for a different board. I am using the Adafruit Feather M0 RFM95 . I would prefer to go the DS18b20 address route given the la…
