*PLEASE NOTE: Until now I did not manage to get this design water proof. Somehow water always finds a way to get in. I tried PLA and PETG. Please let me know if you have any new idea.*

This is my approach to measure the temperature of my pool: a swimming thermometer.

It houses a 16340 battery at the bottom which is fixed with the small piece and is connected with some copper tape. For electronics I used an Arduino pro mini and a RFM95W module to connect to the TheThingsNetwork via LoRa. At the bottom a DS18B20 perfectly fits and can be secured with glue. I used PTFE tape to make the screwed cap water tight.
