The Greenhouse tool is a live data visualization tool developed for a dedicated measurement series conducted in the IMKIFU greenhouse. Its core purpose is to support real-time monitoring of sensor data to ensure data plausibility and enable immediate action in case of sensor malfunction. The system is built on a lightweight MQTT-based data transfer architecture, where measurement devices send data to an internal broker. From there, the data is parsed and stored in a database, making it available for real-time visualization in both a Grafana dashboard and a custom web interface. This setup allows researchers and technicians to track measurements continuously and respond quickly to anomalies—ensuring high data quality throughout the experiment.
