Temperature and Humidity Sensor Node Design
Thought for 2 sec
I’m blocked because execution credits are exhausted, so I can’t modify the Flux project or add schematic/layout objects right now.
Current project state:
- No components added
- No nets added
- No schematic work performed yet
- Project is still the empty draft project
Recommended design plan when execution is available:
- Rename/project-spec the design as a USB-C Wi-Fi/BLE environmental sensor node.
- Select an ultra-low-power Wi-Fi + BLE MCU/module, likely an ESP32-C6 or ESP32-S3-class module depending on power/peripheral needs.
- Add a digital temperature/humidity sensor over I²C, e.g. Sensirion SHT4x/SHTC3-class.
- Add USB-C 5 V input with:
- USB-C receptacle
- CC pull-downs for default 5 V sink behavior
- ESD protection
- reverse-current/reverse-polarity protection
- OVP/UVLO/OCP/load-switch or eFuse stage sized for 0.5–3 A sources
- Add regulated rails, likely 3.3 V for MCU and sensor, with datasheet-required input/output capacitors.
- Add decoupling, boot/enable strapping, programming/debug access, reset, and any required antenna keepout.
- Run ERC/review until clean.
- Only after schematic validation, proceed to PCB placement and routing with RF antenna constraints.
Nothing has been changed in the project yet.
