1. Introduction: Safeguarding Global Food Security

Post-harvest grain loss represents a significant threat to global food security and economic stability, with estimates suggesting that between 9% and 20% of stored grain is lost annually due to spoilage, pests, and suboptimal environmental conditions [1]. For a large-scale facility with a storage capacity of 5,000 tons, this can translate to financial losses exceeding hundreds of thousands of dollars. The SOLARTODO Grain Storage Monitoring Full system is an industrial-grade Internet of Things (IoT) solution engineered to mitigate these risks through precision monitoring and data-driven intervention. By providing real-time, comprehensive insights into the grain silo environment, this system empowers facility managers to preserve grain quality, prevent spoilage, and optimize operational efficiency. This document provides a detailed technical examination of the system's architecture, capabilities, and adherence to international standards, designed for agricultural engineers, storage facility operators, and technology integrators.

2. System Architecture and Components

The Grain Storage Monitoring Full system is a fully integrated solution designed for comprehensive coverage of facilities up to 5 hectares. It comprises three core elements: a distributed network of advanced sensor nodes, a central communication gateway, and a professional-tier cloud analytics platform. The standard configuration includes 30 multi-parameter sensor units, strategically deployed to create a high-resolution, three-dimensional map of the storage environment.

• Sensor Network: The system utilizes a combination of multi-point temperature cables and standalone multi-parameter nodes. The temperature cables, extending up to 25 meters in length, feature sensors spaced every 2 meters to create a detailed thermal profile of the grain mass from top to bottom. The 30 dedicated sensor nodes are placed at critical locations to monitor a full spectrum of atmospheric and biological indicators.
• Communication Gateway: Data from all 30 sensors is aggregated by a central gateway unit. This model features dual WiFi and Ethernet connectivity, ensuring reliable, high-bandwidth data transmission with latency under 50 milliseconds. The gateway, compliant with IEC 62443 standards for industrial network security, acts as the secure bridge between the on-site hardware and the cloud platform.
• Cloud Platform: The Professional Cloud Tier provides the analytical engine for the system. It ingests data from the gateway, offering unlimited data retention, advanced visualization tools, and AI-driven predictive analytics. The platform is built on a microservices architecture, ensuring 99.95% uptime and scalability to handle thousands of data points per minute.

3. Core Monitoring Capabilities

The system offers a comprehensive suite of monitoring parameters critical for maintaining optimal grain condition. This multi-faceted approach moves beyond simple temperature checks to provide a holistic view of the storage ecosystem, enabling proactive management of spoilage risks.

The system's 30 sensors provide granular data, allowing for the creation of detailed 3D heatmaps and gas concentration gradients within a 5,000-ton silo. This spatial resolution is crucial for detecting localized "hot spots" – pockets of high temperature and moisture that are precursors to widespread spoilage – with a spatial accuracy of less than 0.5 cubic meters.

4. Data Acquisition and Communication

Reliable and timely data is the cornerstone of effective storage management. The system is configured for a default data transmission interval of 10 minutes, which is user-configurable from 1 to 60 minutes to balance data granularity with network load. Each sensor node is equipped with an internal memory buffer capable of storing up to 72 hours of data (432 data points at a 10-minute interval). In the event of a network disruption, the nodes continue to log data and will automatically retransmit the stored information once connectivity to the WiFi/Ethernet gateway is restored, ensuring zero data loss.

The gateway communicates with the cloud platform via a secure, TLS 1.3 encrypted channel. For seamless integration with existing farm management software (FMS) or enterprise resource planning (ERP) systems, the platform provides a comprehensive REST API. The API, documented with OpenAPI 3.0 specifications, allows third-party systems to pull raw sensor data, retrieve analytical results, and even configure alert parameters. This adherence to open standards ensures interoperability and future-proofs the investment, preventing vendor lock-in.

5. Cloud Platform and AI Analytics

The Professional Cloud Tier transforms raw data into actionable intelligence. The platform features a real-time dashboard that is accessible via any web browser or dedicated mobile application. Key features include:

• Real-Time Visualization: Users can view live readings from all 30 sensors, visualize temperature distribution through 3D heatmaps, and track historical trends for any parameter over user-defined timeframes.
• AI-Powered Alerts: The system moves beyond simple threshold-based alarms. The AI engine analyzes the rate of change and interdependencies between multiple parameters. For example, it can distinguish between a gradual, uniform temperature increase due to ambient conditions and a rapid, localized spike in both temperature and CO₂ that strongly indicates microbial activity. This predictive capability provides alerts up to 48 hours before a spoilage event becomes critical.
• Automated Reporting: The platform can generate daily, weekly, or monthly reports in PDF format, summarizing storage conditions, highlighting anomalies, and documenting all alert events. These reports are crucial for quality assurance, regulatory compliance (e.g., HACCP), and insurance purposes.
• Yield & Quality Forecasting: By correlating storage conditions with historical data, the AI model can forecast the expected quality degradation over time, allowing for more strategic inventory management and sales decisions. It can predict the percentage of grain that will remain within a specific quality grade (e.g., U.S. No. 1 Hard Red Winter wheat) after 6 months of storage with a projected accuracy of 95%.
