In this extract from From sensors to smart decisions: the data-driven revolution in precision viticulture, Raul Morais from CITAB/UTAD University of Tras-os-Montes e Alto Douro, the speaker explores the role of digital technologies and sensor networks in improving irrigation efficiency in viticulture, with a focus on data integration, adaptability, and low-cost implementation.
The speaker begins by highlighting the explosion of heterogeneous data—not just “big data,” but what is now a “data lake” from many sensor types.
The challenge is not just collecting data but analyzing and integrating it to generate useful insights.
They emphasize that there is no universal communication technology for agricultural sensors. Each technology—whether LoRaWAN, Wi-Fi, GPRS, or Bluetooth—has strengths and should be chosen based on the specific use case.
Their research group has developed a Solar Powered Wireless Acquisition Station, a flexible device capable of connecting to multiple types of sensors and transmission protocols. This has been applied in the PIMAPT project, aimed at optimizing irrigation practices.
Key points covered :
- A low-cost sensor system was developed
- Field experiments tested four irrigation regimes
- Data from soil moisture sensors and vine stress indicators (like the Crop Water Stress Index) allowed assessment of water-use reduction without yield loss
- LoRaWAN-based devices successfully collected transpiration data and integrated it into the mySENSE platform for analysis
This work shows how real-time sensing and smart data analytics can drive sustainable water management in vineyards—crucial under growing environmental pressures.
The takeaway: Adaptable, integrated sensor systems are key to precision irrigation, supporting both environmental and economic sustainability.
