These are research-stage component candidates, not a verified kit. Checking a part does not establish electrical compatibility, supplier stock, or purchase eligibility.

02 / THE APPROACH

Build sequence.

01
Verify the BME280 wiring and supply.
02
Read temperature and humidity.
03
Publish a small read-only local dashboard.
04
Mark stale readings and connection failures.
05
Optionally add a separately qualified soil probe.

⚑ ENGINEERING NOTE

Ambient humidity is not soil moisture. Do not infer watering status without a soil sensor.

Concept-stage plan; bench validation and firmware QA pending.
