Temperature and Humidity Sensor Node设计
Make me a temperature and humidity sensor node with Wifi and Bluetooth, powered by USB-C (5V) for consumer use.
It should be a low-power environmental node with a digital T/RH sensor, ultra-low-power MCU with Wi-Fi + Bluetooth (dual-radio) — 2.4 GHz 802.11 b/g/n plus BLE 5.x powered by USB-C (5 V) — USB-C receptacle 5 V default; include reverse/OVP/UVLO/OCP protection and plan for 0.5–3 A sources.
Thought for 2 sec
I can’t execute project changes right now because there are no available ACUs for AI actions in this workspace.
Accomplished so far:
- No schematic, BOM, layout, or project files have been created yet.
- The project is still empty: 0 components, 0 nets.
Remaining work:
- Select a suitable ultra-low-power Wi-Fi + BLE 5.x MCU/module, likely an ESP32-C6/C3/S3-class module depending on power/security needs.
- Select a digital temperature/RH sensor, e.g. Sensirion SHT4x/SHTC3-class or similar.
- Design USB-C 5 V input with CC pull-downs, reverse protection, OVP, UVLO, OCP/current limiting, and 0.5–3 A source tolerance.
- Add 3.3 V regulation sized for Wi-Fi transmit current peaks.
- Add programming/debug interface, reset/boot strapping, decoupling, test points, and optional status LED.
- Create schematic, power budget, firmware notes, bring-up plan, regulatory notes for consumer wireless use, then proceed to PCB placement/routing.
When ACUs are available, I can build the full design directly in this project.
