This paper presents the design, implementation, and evaluation of a low-cost, scalable smart
greenhouse monitoring system using ESP8266 (NodeMCU), DHT11, and LDR sensors integrated with
Firebase Realtime Database and a Flutter-based mobile application. The system continuously monitors
temperature, humidity, and light intensity, enabling real-time data access and analysis through cloud
services. Over a one-month period, sensor data was collected and analyzed to identify environmental
patterns and correlations. Results demonstrate effective system performance in monitoring conditions
critical for plant health. Recommendations for future automation and machine learning integration are
proposed.
