Source summary
Develop an affordable, rugged, low-power farm-to-fork sensor node for SMEs logging temperature, humidity and ethylene during transit. Retain cryptographically protected local records through cellular outages and automatically sync encrypted data to a decentralised ledger when connected, using lightweight protocols such as MQTT. Include plug-and-play use and solar/thermal harvesting for extended battery life. Resistance to moisture, dust and vibration is required; indefinite life and manipulation prevention are design aspirations needing demonstration.
