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.

You want a low-power USB-C temperature/humidity sensor node with Wi-Fi + BLE for consumer use.
I've built the plan:
  1. Add USB-C 5 V sink power entry plus reverse/OVP/UVLO/OCP protection.
  2. Add the digital T/RH sensor and dual-radio ultra-low-power MCU.
  3. Add required support circuitry and power conditioning.
  4. Review the schematic against your low-power and consumer-use requirements.
