Temperature and Humidity Sensor Node Design

Make me a temperature and humidity sensor node with Wifi and Bluetooth, powered by USB-C (5V) for consumer use.
It should be a low-power environmental node with a digital T/RH sensor, ultra-low-power MCU with Wi-Fi + Bluetooth (dual-radio) — 2.4 GHz 802.11 b/g/n plus BLE 5.x powered by USB-C (5 V) — USB-C receptacle 5 V default; include reverse/OVP/UVLO/OCP protection and plan for 0.5–3 A sources.

I can’t modify the project right now because your account has no available ACUs, so AI execution features are unavailable.
Current project state: the project is still empty — 0 components and 0 nets — and no schematic/layout work has been performed in this session.
What remains to be done once ACUs are available:
  • Create a project specification for the USB-C powered Wi‑Fi/BLE temperature/humidity node.
  • Select the MCU/module, likely an ultra-low-power Wi‑Fi + BLE 5.x module, and a digital temperature/RH sensor.
  • Design the USB-C 5 V input with CC pull-downs, reverse protection, OVP, UVLO, OCP, and support for 0.5–3 A sources.
  • Add 3.3 V regulation, decoupling, programming/debug access, status LED, and test points.
  • Create schematic, run ERC/design review, then proceed to PCB placement/routing and regulatory/bring-up documentation for consumer wireless use.
