Mike Barrow of Costa Flores winery in Mendoza, Argentina, published a very detailed step-by-step guide how to build a soil moisture sensor network using Vinduino boards and a Raspberry Pi as LoRa gateway as part of his project.
The Openvino project is transforming the Costaflores Organic Vineyard, bringing the Internet of Things to the Internet of Vines. Mike Barrow explains how low-cost technologies provide "extreme transparency and traceability", a window into the day-to-day operations of this small Argentine vineyard in this video: https://youtu.be/DlqX9lzcBcI
