Known Engineering Constraints & Bench Boundaries
All projects are built from real bench testing and validated by automated static analysis and continuous integration. Note the following operational boundaries:
- DS3231 backup coin-cell battery powers RTC during main power outages.
- DHT22 sampling interval should not be lower than 2.0 seconds.
- Captive portal automatically enters sleep mode after Wi-Fi credential provisioning.
