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’ll create a low‑power USB‑C 5 V Wi‑Fi/BLE temperature‑humidity node with protection, 3.3 V regulation, I2C sensing, and RF‑aware placement.
  • Power: add USB‑C receptacle, protection, 5 V→3.3 V regulation, and ESD.
  • Compute: add Wi‑Fi+BLE module with decoupling and programming.
  • Sense: add digital T/RH sensor on I2C, 100 nF bypass, 4.7 k pull‑ups.
  • Connect nets, then place with antenna keepout and sensor thermal isolation.
Before I start:
  1. Do you prefer a certified RF module (on‑board antenna) or a bare SoC?
  2. Sensor accuracy class (for RH/Temp)?
  3. USB is power‑only, correct—no data to MCU?
