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 1 sec
I can’t execute design changes right now because this account has no available ACUs, so AI project-editing features are unavailable.
Nothing has been added to the project yet; it is still an empty draft with 0 components and 0 nets. Remaining work is to create the schematic for the USB-C powered Wi-Fi/BLE temperature/humidity node, including: USB-C 5 V input with CC resistors, reverse/OVP/UVLO/OCP protection sized for 0.5–3 A sources, power regulation, ultra-low-power dual-radio MCU/module, digital T/RH sensor, required passives/decoupling, RF/antenna keepout guidance, validation checks, and consumer-use documentation such as bring-up and regulatory notes.
