This study implements 4.0 technologies, specifically the Internet of Things (IoT), alongside descriptive and diagnostic analysis
techniques to monitor agro-environmental variables affecting coffee cultivation at Las Acacias farm, Salento, Quindío. The
objective was to optimize the management of grain production processes through an intelligent system for data collection and
analysis. A star-topology sensor network was designed, consisting of two nodes located at a maximum distance of 120 meters from
the Gateway. The selected sensors DHT22 (temperature and humidity), FC-28 (soil moisture), and EC-5 (electrical conductivity)
were evaluated based on accuracy, reliability, ease of configuration, and cost. Data transmission was carried out using the
LoRaWAN protocol and managed via the IoT platforms The Things Network (TTN) and TAGOIO, with measurement intervals set
every 10 minutes.
The results indicated that high maximum temperatures (38.1°C in September) and low relative humidity (21.7% in August)
triggered thermal and water stress conditions in coffee plants, affecting key physiological processes. A decline in soil water content
and electrical conductivity revealed a water deficit and potential nutrient leaching, highlighting the need to adjust fertilization
practices through irrigation systems and agronomic management strategies. Finally, this study demonstrates that the integration of
IoT sensors with data analysis techniques enables timely and well-founded decision-making, fostering the adoption of precision
agriculture, crop sustainability, and improved coffee productivity.
