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 and digital temperature/RH sensor, design the protected USB‑C 5 V power path and regulation, capture and verify the schematic, then create and validate the RF-aware PCB layout.
