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.
Thought for 2 sec
I’m blocked because execution credits are exhausted, so I can’t modify the project or add the schematic components right now.
Current project state:
- Empty project: 0 components, 0 nets.
- Draft placeholder name is still set.
- No schematic, PCB layout, or validation has been created yet.
What remains to build:
- Select a low-power Wi‑Fi + BLE 5.x MCU/module, likely an ESP32-C3/S3/C6-class module depending on power/peripheral needs.
- Select a digital temperature/RH sensor, preferably I²C with low standby current.
- Design USB‑C 5 V input with default-current CC resistors, ESD protection, reverse-current/OVP/UVLO/OCP protection, and current planning for 0.5–3 A USB-C sources.
- Add regulated power rails, decoupling, boot/programming circuitry, sensor pull-ups, and connectors/debug access.
- Verify all IC wiring against datasheets, run ERC/review, then proceed to layout only after schematic confirmation.
