USB-C Sensor Node
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 2 sec
I can’t execute design changes right now because this account has no available ACUs, so AI project-editing features are unavailable. Nothing has been added to the project yet; it is still an empty draft project with 0 components and 0 nets.
What remains to be done once ACUs are available:
- Create the project specification for a consumer USB-C powered Wi‑Fi/BLE temperature/humidity sensor node.
- Select parts: low-power Wi‑Fi + BLE 5.x MCU/module, digital T/RH sensor, USB-C receptacle, input protection/power-path ICs, regulator, ESD/TVS, passives, and programming/debug interface.
- Design the schematic with USB-C 5 V default power, reverse/OVP/UVLO/OCP protection, 0.5–3 A source handling, regulated MCU/sensor rails, RF keepout, and sensor placement considerations.
- Run ERC/design review and prepare next steps for PCB layout, bring-up, firmware pin map, and consumer compliance planning.
