Temperature and Humidity Sensor 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’t start executing the design because this account currently has no available ACUs, so AI project actions are unavailable right now. Nothing has been added or changed in the project yet; it is still an empty new project.
What remains to be done once ACUs are available:
- Select the Wi‑Fi/BLE MCU/module, likely an ESP32-class certified module for consumer 2.4 GHz 802.11 b/g/n + BLE 5.x.
- Select a digital temperature/RH sensor, USB‑C receptacle, 5 V input protection/power-path parts, and regulator architecture.
- Create the schematic with USB‑C 5 V default CC resistors, reverse/OVP/UVLO/OCP protection, 0.5–3 A source planning, 3.3 V rail, MCU, sensor, programming/debug, and status indicators.
- Add low-power design notes, regulatory documentation for wireless consumer use, and a bring-up/test plan.
- Then proceed to PCB layout with antenna keepout, USB-C placement, power-path routing, and sensor thermal/isolation placement.
