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 sec
I can’t start executing the design right now because this account has no available ACUs, so AI project mutation tools are unavailable.
Nothing has been added yet: the project is still empty with 0 components and 0 nets. Remaining work is to create the schematic for a USB-C powered Wi-Fi/BLE temperature-humidity node, including USB-C 5 V input, CC pull-downs, reverse/OVP/UVLO/OCP protection sized for 0.5–3 A sources, 3.3 V regulation, a low-power Wi-Fi/BLE MCU/module, digital T/RH sensor, decoupling, programming/debug access, and consumer-use documentation/checks.
Suggested next steps once ACUs are available:
- Select the MCU/module, likely an ESP32-C3/C6/S3 class module depending on BLE/Wi-Fi requirements.
- Select a digital T/RH sensor such as SHT4x, HDC302x, or equivalent.
- Build and verify the power tree and USB-C protection front end.
- Create the schematic, firmware pin map, bring-up plan, and regulatory documentation.
