Vermicomposting is a sustainable method for organic waste management, but traditional approaches require continuous monitoring to maintain optimal conditions for worm activity and compost quality. This paper presents the design and implementation of an automated vermicomposting system that integrates embedded sensors and microcontroller-based real-time control to optimize environmental parameters. The system uses an ESP32-S3 microcontroller as the core controller, along with soil moisture and temperature sensors, to monitor and regulate irrigation and ventilation through relays and actuators.
Moisture and temperature thresholds are set based on optimal worm activity (60–80% soil moisture and 18–28°C temperature range), and real-time data processing dynamically adjusts system operations to maintain ideal composting conditions.
Collected data are logged and transmitted wirelessly via WiFi/Bluetooth, enabling remote monitoring and analysis through mobile or web applications. Experimental results demonstrate that the automated system consistently maintains optimal conditions, resulting in improved worm productivity and a 15–20% increase in compost yield compared to manual methods. The proposed design offers a reliable, scalable, and energy-efficient solution for high-quality vermicomposting, reducing manual intervention while enhancing sustainability.
Introduction
Vermicomposting transforms organic waste into nutrient-rich compost using worms, but traditional manual methods are labor-intensive, inconsistent, and difficult to scale. Maintaining optimal conditions—such as soil moisture, temperature, and aeration—is critical for worm activity and compost quality.
Automated Vermicomposting:
Automated systems use microcontrollers (e.g., ESP32-S3) and sensors to monitor and control key environmental parameters in real time. These systems regulate irrigation and ventilation, maintain stable conditions, improve worm health, and enhance compost quality. Wireless monitoring and data logging enable remote tracking, predictive maintenance, and long-term optimization.
Literature Insights:
Studies show that IoT-based vermicomposting outperforms manual systems by producing higher-quality compost and sustaining more consistent worm populations. Key challenges include sensor accuracy, stable environmental control, reliable integration, and automated data management.
Methodology:
The system monitors soil moisture and temperature continuously, automatically triggering irrigation and ventilation via relays and actuators. Organic waste is shredded and loaded into the compost chamber, where real-time adjustments maintain ideal conditions for worm activity. Harvesting is optimized using sensor data to separate worms and extract high-quality vermicast efficiently.
Design & Experimentation:
The system maintains soil moisture between 60–80% and temperature between 18–28°C. Low-power sensor circuitry ensures continuous operation, while automated control reduces manual labor and increases compost yield. Overall, the approach offers a scalable, efficient, and sustainable solution for organic waste management.
Conclusion
Automated vermicomposting systems, driven by embedded sensors and real-time control, enhance both the output and consistency of compost while significantly reducing operational overhead. Future developments could incorporate advanced data analytics, including machine learning for predictive optimization, modular scalability for larger or distributed operations, and further cost reductions to encourage wider adoption of these sustainable systems.
