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.

No design changes were made; the project remains empty because no ACUs are currently available for AI execution.

Remaining work:

Select the Wi‑Fi/BLE MCU, digital temperature/RH sensor, and protected 5 V power architecture.
Design USB‑C default-power input with CC resistors, reverse-current protection, OVP, UVLO, OCP, ESD protection, and support for 0.5–3 A capable sources without assuming USB‑PD.
Add regulation, decoupling, programming/debug, boot controls, antenna keepout, and sensor thermal-isolation provisions.
Capture and verify the schematic, then complete PCB placement, routing, ERC/DRC, power analysis, and consumer compliance notes.
