USB-C Temperature and Humidity 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 3 sec
I can’t execute design changes right now because this workspace has no available ACUs, so AI project tools are unavailable.
Current project state:
- New empty project:
Bad Coral Wall-E - Components: 0
- Nets: 0
- No schematic, PCB, or documentation has been created yet.
Remaining work once ACUs are available:
- Rename/describe the project for a USB-C Wi‑Fi/BLE temperature-humidity sensor node.
- Select an ultra-low-power dual-radio MCU/module, likely an ESP32-C3/S3-class or similar certified Wi‑Fi 2.4 GHz + BLE 5.x module.
- Select a digital temperature/RH sensor, USB-C receptacle, power-path protection with reverse/OVP/UVLO/OCP, 5 V to 3.3 V regulation, ESD protection, programming/debug interface, and test points.
- Build and verify the schematic.
- Create power budget, firmware pin map, bring-up plan, and consumer-use regulatory/compliance notes.
- Proceed to PCB placement/routing with antenna keepout, USB-C protection layout, and power integrity constraints.
