Wi-Fi/Bluetooth Environmental 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.
Thought for 1 sec
I can’t start modifying the project because AI execution is currently unavailable due to no available ACUs.
Nothing has been added yet: the project is still empty with 0 components and 0 nets. To complete your requested USB-C powered Wi‑Fi/Bluetooth temperature/humidity sensor node, the remaining work is:
- Define the architecture and rename/document the project.
- Select a dual-radio low-power MCU/module, likely an ESP32-C6/S3-class module depending on BLE/Wi‑Fi requirements.
- Select a digital temperature/RH sensor.
- Design USB-C 5 V input with default CC pull-downs and protection: reverse protection, OVP, UVLO, OCP/current limiting, and ESD.
- Add regulated rails, likely 3.3 V for MCU/sensor, sized for Wi‑Fi transmit peaks and 0.5–3 A source compatibility.
- Add required decoupling, boot/programming circuitry, antenna keepout, and sensor placement considerations.
- Run schematic validation/ERC, then create bring-up, firmware, and regulatory documentation before moving to PCB layout.
Once ACUs are available, I can build and verify the schematic in the project.
