Ground Temperature and Moisture Logger
Long term ground temperature and moisture monitoring and logging.
Installed to monitor ground temperature and moisture at a proposed vineyard site. The data is written to the onboard SD card and sent via LoRa back to a base station from where it is stored in an SQL database running on an raspberry pi3. It is then displayed on a Node-red dashboard.
