Temperature and Humidity Sensor Design
Thought for 3 sec
I’m blocked because execution credits are exhausted, so I can’t modify the project or run design tools right now.
Current project state:
- Project is still empty: 0 components, 0 nets.
- No schematic, layout, review, or documentation changes have been made yet.
What remains to be done when credits are available:
- Rename the draft project and create a project specification.
- Select a suitable ultra-low-power Wi-Fi + BLE 5.x MCU/module, likely an ESP32-C6 / ESP32-C3-class module depending on power and feature priorities.
- Select a digital temperature/RH sensor, likely I²C, with consumer-grade accuracy.
- Design the USB-C 5 V input stage:
- USB-C receptacle with CC pull-downs for default 5 V sink behavior.
- Input ESD protection.
- Reverse protection.
- OVP, UVLO, and OCP/load-switch protection sized for 0.5–3 A sources.
- Add power regulation from USB-C 5 V to the MCU/sensor rail, likely 3.3 V, with power-budget sizing.
- Wire MCU, sensor, USB-C power, boot/programming, reset, antenna keepout, decoupling, and test points per datasheets.
- Run schematic review/ERC and fix all violations.
- Create bring-up and firmware pin-mapping documentation.
- After schematic approval, proceed to PCB placement, then request confirmation before routing.
