USB-C Sensor Node

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 design changes right now because this account has no available ACUs, so AI project actions are unavailable. No schematic or PCB changes have been made yet; the project is still empty.
What remains to be done once ACUs are available:
  • Create the project specification for a USB-C powered Wi-Fi/BLE temperature/humidity sensor node.
  • Select the MCU/module, likely an ultra-low-power Wi-Fi + BLE 5.x module such as ESP32-C6/ESP32-S3 class depending on requirements.
  • Select a digital T/RH sensor, USB-C receptacle, protection/power-path parts, 3.3 V regulator, ESD/OVP/OCP/UVLO circuitry, and passives.
  • Build the schematic with USB-C 5 V default CC resistors, reverse/OVP/UVLO/OCP protection sized for 0.5–3 A sources, 3.3 V regulation, sensor I2C, programming/debug, and RF layout constraints.
  • Add bring-up, firmware, power-budget, and regulatory/FCC/CE planning documentation for a consumer wireless product.
