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 1 min 7 sec
I’ll create your low‑power USB‑C (5 V) T/RH node with dual‑radio Wi‑Fi (802.11 b/g/n 2.4 GHz) + BLE 5.x, including reverse/OVP/UVLO/OCP on the input and support for 0.5–3 A sources.
Plan summary:
- Key ICs: add an ultra‑low‑power Wi‑Fi+BLE MCU and a digital I2C T/RH sensor with required pull‑ups and passives.
- USB‑C power-in: place a USB‑C receptacle (power‑only), CC resistors, ESD/EMI parts; add an eFuse/power‑switch for reverse/OVP/UVLO/OCP.
- Power rails: design a high‑efficiency 3.3 V regulator from 5 V with bulk and local decoupling; budget active/standby currents.
- Control & IO: add programming/debug header, status LED(s), reset/boot circuitry; define nets between MCU, sensor, and power path.
- PCB: reserve antenna keep‑out and matching, place sensor for airflow and thermal isolation; run auto‑layout and reviews; finalize BOM and availability.
