Sub-GHz Weather Node

Battery-powered weather telemetry over a private sub-GHz link. Battery-powered weather telemetry over a private sub-GHz link.

Components

• Sub-GHz sensor node
• receiver
• antenna metadata

Build steps

1. Inventory the board, actuators, sensors, and power rails listed for W07.
2. Build and inspect the low-voltage wiring against the supplied connection diagram before connecting actuators.
3. Flash the firmware, run the startup self-check, and record the printed board and firmware version.
4. Calibrate the sensors and limits, then run the acceptance tests at the lowest safe energy level.

Test and expected result

Range, antenna orientation, packet integrity, and local regulation compliance.

Safety and limits

Use permitted frequencies and power levels.
