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 design mutations right now because this account has no available ACUs, so AI project actions are unavailable. No schematic, components, nets, PCB layout, or project documents have been created yet; the project is still empty with the placeholder name “Northern Amethyst Massive Robot Spider.”
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 a dual-radio ultra-low-power MCU/module, likely an ESP32-C6/S3-class module depending on Wi-Fi/BLE priorities and certification needs.
  • Select a digital T/RH sensor, USB-C receptacle, input protection/load switch/eFuse with OVP/UVLO/OCP/reverse-current protection, and 3.3 V regulation.
  • Design the schematic: USB-C 5 V default sink, CC pulldowns, protection path for 0.5–3 A sources, 3.3 V rail, MCU, sensor, programming/debug, status LED, and test points.
  • Add consumer-product considerations: certified radio module, antenna keepout, ESD protection, labeling/regulatory notes, and bring-up plan.
  • Verify ERC/design rules and then proceed to PCB placement/layout with RF antenna keepout and power-path routing constraints.
