Temperature and Humidity Sensor Node Design
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 design this, but I’m currently blocked because this account has no available ACUs, so I can’t mutate the project or run Flux AI design tools right now.
Current project state:
- New empty project created:
Digital Olive Transporter - Components: 0
- Nets: 0
- No schematic, PCB layout, or documentation has been added yet.
What remains to be done once ACUs are available:
- Rename and document the project as a USB-C powered Wi‑Fi/BLE temperature-humidity sensor node.
- Select an ultra-low-power Wi‑Fi + BLE 5.x MCU/module, likely an ESP32-C3/S3-class module depending on GPIO, power, and certification needs.
- Add a digital temperature/RH sensor, USB-C power input, CC resistors, input protection, reverse/OVP/UVLO/OCP power path, and 3.3 V regulation sized for 0.5–3 A USB-C sources.
- Create the schematic, power budget, firmware pin map, regulatory notes for consumer wireless use, bring-up plan, and then proceed to PCB placement/routing.
