Temperature and Humidity Sensor Node Design
Thought for 4 sec
I’m blocked because project execution credits are exhausted, so I cannot modify the schematic, add components, consult datasheets, or run validation.
Current project state:
- No schematic work has been performed.
- Project is still empty: 0 components, 0 nets.
- No datasheets, ERC, layout, or review checks have been run.
Recommended design plan when execution is available:
- Rename the project and create a design spec for the USB-C Wi-Fi/BLE environmental sensor node.
- Select an ultra-low-power Wi-Fi + BLE 5.x MCU/module, likely an ESP32-C3/S3-class module or equivalent dual-radio certified module.
- Add a digital temperature/humidity sensor over I²C.
- Design USB-C 5 V input with:
- USB-C receptacle configured for default 5 V sink operation
- CC pull-down resistors
- ESD protection
- Reverse-current / reverse-polarity protection
- OVP, UVLO, and OCP / current-limit protection
- Support planning for 0.5–3 A USB-C sources
- Add regulated rails, likely 3.3 V for MCU and sensor, sized from a full power budget.
- Add all required decoupling, pull-ups, boot straps, programming/debug connector, and antenna keepout.
- Run schematic review/ERC and fix all violations before moving to layout.
Once credits are available, this should start with component selection and datasheet-grounded power budgeting before any schematic wiring.
