Temperature and Humidity Sensor Node Design

dxw1999

dxw1999

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 actions are unavailable.
Nothing has been added to the project yet; it is still an empty new project with 0 components and 0 nets. Remaining work once ACUs are available: create the project spec, select the Wi‑Fi/BLE MCU and digital temperature/humidity sensor, design the USB‑C 5 V input with CC resistors plus reverse/OVP/UVLO/OCP protection sized for 0.5–3 A sources, add regulation/power budgeting, wire the schematic, then run ERC/design review and create bring-up/regulatory notes for consumer use.
