TECHNICAL SPECIFICATION: THE LOOM NODE V1.0

Project Code: LC-AgriLink | 

Protocol: Blockchain-Verified Mass Telemetry

1. SYSTEM ARCHITECTURE

The Loom Node is not a simple scale; it is an Edge-Computing Waste Monitor. It utilizes a "Sense-Verify-Anchor" logic flow to ensure data cannot be falsified by staff or external parties.

2. CORE HARDWARE COMPONENTS

• The Brain (ESP32-WROOM): A dual-core 240MHz processor. It handles complex signal filtering to ensure that greenhouse vibrations or marina wind gusts do not cause "weight drift."

• The Sensors (4x 50kg Parallel Beam): Arranged in a Wheatstone Bridge configuration, these industrial-grade load cells provide a 200kg capacity with 100g resolution.

• The Signal Chain (HX711): A 24-bit Analog-to-Digital converter that captures the microscopic voltage changes from the weight of the plastic and turns them into clean digital data.

• The Uplink (SIM7080G LTE-M): Specifically selected for its "Industrial Penetration" capabilities. It allows the bin to transmit through metal winery buildings or from remote greenhouse corners where standard Wi-Fi fails.

3. THE "LOOM MOAT" (SECURITY PROTOCOL)

1. On-Board Hashing: Before the data leaves the bin, the ESP32 runs a SHA-256 Cryptographic Hash. This creates a unique "Digital Fingerprint" of the weight event.

2. Blockchain Anchoring: This fingerprint is pushed to the Polygon Network.

3. Audit Immunity: Once anchored, the record is Immutable. Even if the central database is compromised, the original record remains verified on the blockchain, providing 100% legal protection for the facility during an ECCC audit.

 The Technical Moat

1. Sensing: ESP32 + 24-bit ADC + Load Cell Array (Source Verification).

2. Hashing: SHA-256 hash created at the "Edge" to prevent data tampering.

3. Anchoring: Data is pushed to the Polygon blockchain (Loom Ledger).

4. Logistics: LTE-M telemetry triggers the Ford Transit only when the bin is at 85% capacity.
