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 can’t execute project edits right now because this account has no available ACUs, so AI design actions are unavailable.
Current project state:
  • New empty project created: Variable Teal R2-D2
  • No components, nets, schematic, PCB layout, or documentation have been added yet.
What remains to build your sensor node:
  • Select the Wi-Fi + BLE MCU/module, likely an ESP32-class module for 2.4 GHz Wi-Fi b/g/n + BLE 5.x.
  • Select a digital temperature/RH sensor, likely I²C.
  • Design USB-C 5 V input with CC pull-downs, reverse protection, OVP, UVLO, OCP/current limiting, and 0.5–3 A source tolerance.
  • Add 3.3 V regulation sized for Wi-Fi TX current peaks.
  • Add schematic, decoupling, programming/debug access, test points, bring-up notes, regulatory notes, and PCB antenna keepout/layout constraints.
Once ACUs are available, I can create the full schematic and supporting project docs.
