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 mins 20 sec
I’ll build a low‑power USB‑C (5 V) environmental node with dual‑radio Wi‑Fi + BLE and a digital T/RH sensor.
- Add certified Wi‑Fi+BLE module, digital T/RH sensor, USB‑C sink (CC) and ESD.
- Add input protection (reverse, OVP/UVLO/OCP), TVS; 5 V→3.3 V high‑efficiency supply; decoupling.
- Wire I2C with pull‑ups; add reset/boot and status LED; enforce antenna keep‑out; place sensor at vent.
- Run ERC/DRC and availability checks.
