Wi-Fi and Bluetooth 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.
Thought for 5 sec
I haven’t made any project changes yet: the schematic is still empty with 0 components and 0 nets.
I’m currently blocked because your account has no available ACUs, so AI design actions are unavailable and I can’t add components, wire the schematic, consult datasheets, or run review checks.
What remains to be done once ACUs are available:
- Rename/describe the project for the USB-C Wi-Fi/BLE T/RH sensor node.
- Select a dual-radio ultra-low-power MCU/module with 2.4 GHz Wi-Fi 802.11 b/g/n + BLE 5.x.
- Select a digital temperature/humidity sensor.
- Design the USB-C 5 V input with CC resistors, reverse protection, OVP, UVLO, OCP/current limiting, and support for 0.5–3 A sources.
- Add regulated power rails, decoupling, programming/debug access, and any required boot/configuration circuitry.
- Verify the schematic against datasheets and run electrical review.
- Create bring-up, firmware, and regulatory documentation for the consumer wireless product.
