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 execute project changes right now because this account has no available ACUs, so AI design tools are unavailable. Nothing has been added to the project yet; it is still an empty new project with 0 components and 0 nets.
What remains to be done once ACUs are available:
  • Create a project specification for the USB-C powered Wi-Fi/BLE temperature-humidity sensor node.
  • Select the MCU/module, likely an ESP32-class Wi-Fi + BLE 5.x module, and a digital T/RH sensor.
  • Design USB-C 5 V input with CC resistors, reverse/OVP/UVLO/OCP protection, and regulator power tree.
  • Add schematic components, decoupling, programming/debug interface, test points, and protection parts.
  • Run ERC/design review and create bring-up, firmware, and regulatory documentation for consumer use.
