The Bachelor’s thesis explores the integration of IoT and GIS technologies to enhance
decision support for smart agriculture. It identifies core challenges in real-time environ-
mental data collection, visualization, and irrigation planning. A full-stack dashboard
solution was designed using Zentra Cloud APIs, PostgreSQL, Tailwind CSS, and Next.js
to visualize sensor data on a GIS map and calculate evapotranspiration (ET) for water
management.
The dashboard was evaluated through performance tests and field demonstrations.
Results show that the system improves irrigation decision speed, sensor usability, and ET
prediction reliability. The proposed system is suitable for farmers, agronomists, and IoT
developers aiming to implement real-time soil monitoring. No conference presentations
or publications have resulted from this work yet.
