Low-Power Sensor Node Design
Make me a temperature and humidity sensor node with Wifi and Bluetooth, powered by USB-C (5V) for consumer use.
Debe ser un nodo ambiental de bajo consumo con un sensor digital T/RH y un MCU de consumo ultrabaja. with Wi-Fi + Bluetooth (radio dual): 2,4 GHz 802.11 b/g/n más 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 1 min 17 sec
I’ll create a low‑power T/RH sensor node with dual‑radio Wi‑Fi 802.11 b/g/n + BLE 5.x, powered from USB‑C 5 V with full input protection. Plan summary:
- Select parts: ultra‑low‑power Wi‑Fi+BLE MCU/module and a low‑power digital T/RH sensor; add required passives.
- USB‑C input: receptacle, CC resistors, reverse/OVP/UVLO/OCP, inrush/EMI, and ESD/TVS on VBUS/CC.
- Power: efficient 5 V→3.3 V regulator sized for radio peaks; bulk/decoupling; optional quiet sensor rail.
- Integration: connect sensor (I2C), MCU boot/config, clocks, pull‑ups; label nets.
- PCB prep: board size, RF keepouts, preliminary rules; run auto‑layout and initial routing.
