# 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
|
