Temperature and Humidity Sensor 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 design changes right now because this account has no available ACUs, so AI project-editing features are unavailable.
Nothing has been added to the project yet; it is still empty. The requested design would be a USB-C powered low-power Wi-Fi/BLE temperature and humidity sensor node with: ESP32-class dual-radio MCU, digital T/RH sensor, USB-C 5 V input with CC pull-downs, input protection for reverse/OVP/UVLO/OCP, and power-path sizing for 0.5–3 A USB-C sources.
When ACUs are available, the next steps are:
  • Create the project specification and rename the project.
  • Select the MCU/module, T/RH sensor, USB-C connector, protection IC/eFuse, and 3.3 V regulator.
  • Build and verify the schematic, including power budget and bring-up documentation.
  • Lay out the PCB with RF keepout/antenna clearance, USB-C input protection, and sensor thermal isolation.
