Temperature and Humidity Sensor Design
Thought for 2 sec
I’m blocked from executing design actions in the project right now because the session has no remaining execution credits.
Nothing has been added or changed yet. The project is still empty: 0 components and 0 nets.
Recommended next work when credits are available:
- Rename the draft project and create a short design specification.
- Select a dual-radio low-power MCU/module, likely an ESP32-C6/ESP32-S3 class module depending on power and BLE/Wi-Fi requirements.
- Select a digital temperature/RH sensor, e.g. Sensirion SHT4x/SHTC3-class, after checking datasheets.
- Design USB-C 5 V input with:
- USB-C receptacle and CC pull-downs for default 5 V sink behavior
- ESD protection
- reverse-current protection
- overvoltage protection
- UVLO/OCP/load switch or eFuse sized for 0.5–3 A sources
- Add 3.3 V regulation sized from a full power budget, including Wi-Fi TX peaks.
- Wire MCU boot/enable/programming pins, decoupling, antenna keepout, I2C pull-ups, sensor bypassing, and optional debug/programming header.
- Run schematic review/ERC and fix all unresolved violations.
- After schematic approval, proceed to PCB sizing, RF-aware placement, antenna keepout, and routing.
No schematic, layout, or validation has been performed yet.
