Abstract: The increasing demand for sustainable and efficient agricultural practices has driven the adoption of vertical farming systems integrated with IoT-based automation technologies. This study aimed to develop and evaluate a web-based automation system utilizing DHT22 (temperature and humidity sensor), BH1750 (light intensity sensor), MQ-135 (air quality sensor), and soil moisture sensors for real-time environmental monitoring and control in vertical farming structures. The system was designed to autonomously manage temperature, humidity, light intensity, air quality, and soil moisture, using an ESP8266 microcontroller and a web-based interface for data acquisition and control. Data were collected over 60 days and analyzed using statistical tools such as paired t-test, one-way ANOVA, Pearson correlation, and chi-square tests. The results demonstrated significant improvements in environmental parameter stability, with 85% consistency in temperature and humidity control, optimized light intensity across layers, and effective CO₂ regulation. Soil moisture levels were maintained within optimal thresholds, leading to 25% higher crop yield and 15% reduced water consumption compared to manually controlled systems. The findings validate the effectiveness of IoT-based systems in enhancing vertical farming efficiency and productivity. Future research should focus on incorporating machine learning algorithms for predictive control and energy optimization to further refine system performance.
