Temperature and Humidity Sensor Design

flux

I’m blocked because the workspace has no execution credits available, so I can’t add parts, consult datasheets, wire the schematic, or run review checks.
Current project state:
  • Empty project: 0 components, 0 nets.
  • No schematic or layout work has been performed yet.
  • Project still has the placeholder name/description.
What remains to be done when credits are available:
  1. Rename and document the project as a USB-C powered Wi-Fi/BLE temperature-humidity sensor node.
  2. Select a dual-radio low-power MCU/module, likely an ESP32-C6 / ESP32-C3 / ESP32-S3-class module depending on required BLE/Wi-Fi tradeoffs.
  3. Select a digital T/RH sensor with I²C interface and low standby current.
  4. Design USB-C 5 V input with:
    • CC pull-downs for default USB-C sink behavior.
    • Reverse-current / reverse-polarity protection.
    • OVP, UVLO, and OCP protection.
    • Current planning for 0.5 A to 3 A capable USB-C sources.
  5. Add regulated rails, likely 3.3 V for MCU and sensor, with datasheet-required input/output capacitors.
  6. Add decoupling, pull-ups, boot straps, reset/enable circuitry, programming/debug access, and antenna keepout.
  7. Run schematic review/ERC and fix all violations.
  8. After schematic approval, proceed to PCB placement, RF-aware layout, routing, and final DRC.
No design changes were made in the project yet.
