Temperature and Humidity Sensor Design
Make me a temperature and humidity sensor node with Wifi and Bluetooth, powered by USB-C (5V).
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 20 sec
I’ll build your low‑power Wi‑Fi (802.11 b/g/n) + BLE 5.x T/RH node powered from USB‑C 5 V with reverse/OVP/UVLO/OCP and 0.5–3 A source support.
Plan:
-
Add: Wi‑Fi+BLE MCU module, digital T/RH sensor (I2C), USB‑C Receptacle, eFuse, Synchronous Buck Converter, ESD/TVS diode, bulk/decoupling caps (100 nF + 1 µF + 10 µF), I2C 4.7 kΩ pull‑ups, headers/testpoints.
-
Wire: CC1/CC2 Rd, protected 5 V→buck→3V3, I2C to sensor, status LED/reset/boot, proper GND/ESD ties.
-
Set properties/designators, update project description; ERC for I2C pull‑ups/decoupling.
-
PCB: stackup/rules, place with RF keep‑out; AutoLayout and route; DRC/ERC and parts availability review.
Click Start on the plan bar to begin. Quick choices before we proceed:
- MCU module preference (e.g., ESP32‑C3/S3) or any low‑power Wi‑Fi+BLE module?
- Sensor preference (e.g., Sensirion SHT4x series) or any low‑power digital T/RH?
- Power‑only USB‑C (no data), correct?
Select ESP32-C3
