This project is a long run using the LoRaNow Board V0 and The Things Network to check how long a node can stay on only with two AA battery.
The Node starts in April of 2019 and dies in September of 2020, 18 months in total.
The Node sleeps and send data using LoRaWAN each ~10 minutes.
The Arduino code is available here.
The data uses a JSON format and has 3 files with the data group by days, hours, and minutes.
