Edge Device Hardware Requirements

Target Platform: Raspberry Pi 5 + Cellular HAT

Must-Have Features

• Raspberry Pi 5 (or equivalent)
• Cellular connectivity (eSIM preferred for remote provisioning)
• Ability to run a local hotspot during initial setup
• Support for camera input (for analog gauge reading)
• Low power consumption for always-on operation
• Tamper-evident enclosure design
• Easy access hatch for SIM/eSIM without opening main enclosure

Recommended Sensors (MVP)

• Pressure sensors
• Current / amp sensors (inductive)
• Flow meters (pulse or analog)
• Tank level sensors
• Camera for analog dial/needle gauges (optional but supported)

Constraints

• Must work in locations with no reliable Wi-Fi
• Must minimize cellular data usage
• Must support reliable local processing even during internet outages
