Project: Connected Plant Monitor - BOM, firmware, build notes

[polygoku]

Connected Plant Monitor — MAKHEX build log

Current status: Blueprint, not an electrically or mechanically qualified kit.

Purpose: Monitor the ambient conditions surrounding a plant.

Candidate bill of materials

• 1x /esp32-c3-supermini — Wi-Fi controller
• 1x /bme280-sensor — Ambient sensing
• 1x /usb-c-power-kit — Bench supply

Proposed build milestones

1. Verify the BME280 wiring and supply.
2. Read temperature and humidity.
3. Publish a small read-only local dashboard.
4. Mark stale readings and connection failures.
5. Optionally add a separately qualified soil probe.

Improve this guide

• Suggest validated supplier or component substitutions
• Share board revision and software environment
• Post reproducible firmware builds, wiring diagrams and measurements
• Document errors, successful tests and unresolved risks

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

Please be specific and label unverified approaches.
