Global export markets demand strict compliance with international farm-to-fork traceability standards to combat food fraud and track contamination outbreaks. While large agribusiness conglomerates can afford expensive cold-chain tracking systems, Small and Medium Enterprises (SMEs) are priced out. Furthermore, standard telemetry loggers lose connectivity in remote agricultural areas, creating critical blind spots in supply chain records.
Develop an affordable, rugged, tamper-proof hardware IoT device that tracks ambient and cold-chain environmental metrics, stores records securely during connectivity blackouts, and immutably anchors provenance onto a distributed ledger.
Maintaining 30-to-60-day battery endurance under sub-zero refrigerated transit (-20°C to +4°C), surviving harsh vibrations and moisture, and keeping unit BOM under $15-$20 while supporting cryptographic signature generation.
An ultra-low-power embedded sensor node (ESP32/nRF/STM32) monitoring temperature, humidity, shock, and GPS, featuring local flash cryptographic signing, offline store-and-forward mesh/BLE harvesting, and automated blockchain provenance anchoring upon reaching connectivity.
