USB-C Temperature and Humidity Sensor 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.

You want a consumer USB-C powered Wi-Fi/Bluetooth temperature and humidity sensor node.
  • I’ve built the plan to:
    1. Define the system architecture
    2. Implement USB-C 5 V power entry and protection
    3. Add the wireless MCU and digital T/RH sensor
    4. Finalize the schematic for PCB-ready implementation
This follows Flux’s planning/modification workflow guidance . Click Start on the plan bar to have it built.
Add ESD protection
Use ESP32-C6
Set 500mA limit
