This repository contains the hardware and software components of a PIR based tracking device to monitor the usage of local bike trails. The data is sent over LoRaWAN to TTN and from there to a Google Cloud backend which stores the data and provides api endpoints for the data visualization web UI.
All our modules use 1.2.0 but there is a version 1.2.3 avilable. https://github.com/arduino/mkrwan1300-fw
How to upgrade firmware is described in the link above.
