Temperature and Humidity Sensor Design
Thought for 4 sec
I’m blocked because execution credits are unavailable, so I can’t modify the project or add schematic/layout content right now.
Current project state:
- Project is still empty: 0 components, 0 nets.
- No schematic, layout, power tree, or BOM changes have been made yet.
- The project still has the placeholder name/description.
What remains to be done once execution is available:
- Rename the project and create a concise design spec.
- Select a dual-radio low-power Wi-Fi + BLE 5.x MCU/module, likely ESP32-C6 / ESP32-C3 class depending on requirements.
- Select a digital temperature/humidity sensor with low standby current and I²C interface.
- Design USB-C 5 V input with:
- USB-C receptacle
- CC pull-downs for default 5 V sink behavior
- Reverse-current protection
- Over-voltage protection
- Under-voltage lockout
- Over-current protection sized for 0.5–3 A sources
- ESD protection
- Add 3.3 V regulation sized from a full power budget.
- Wire MCU, sensor, power, programming/debug, reset/boot, and required passives per datasheets.
- Add decoupling, pull-ups, RF antenna keepout, and consumer-use protection details.
- Run schematic review/ERC and fix all violations.
- After schematic approval, proceed to PCB placement, then routing after your confirmation.
