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 temperature/humidity node with dual‑radio Wi‑Fi (802.11 b/g/n) + BLE 5.x and full input protection.
Planned steps:
- Select and add MCU/module, digital T/RH sensor, USB‑C, 5 V→3.3 V buck.
- Add reverse/OVP/UVLO/OCP (eFuse/ideal diode), CC sink resistors, core nets.
- Add passives: decoupling/bulk, pull‑ups, ILIM/sense, ESD/EMI parts.
- PCB: RF edge keep‑out, thermally isolate sensor; auto‑place/route.
- ERC/DRC review, parts availability, export fab files.
Before I start:
- Do you prefer a radio module (integrated antenna) or chip + antenna?
- Is USB data needed for firmware/programming, or power‑only USB‑C?
- Any sensor accuracy/brand preference (e.g., Sensirion SHT4x), or OK with typical ±1.5% RH?

- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
