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 3 sec
I haven’t made any design changes yet. Your project is still empty with 0 components and 0 nets, and it still has the draft placeholder name “Upset Salmon Sonic Screwdriver.”
I’m currently unable to execute schematic/layout work because this account has no available ACUs, so AI project mutations are unavailable right now.
What remains to be done once ACUs are available:
- Create a project specification for the Wi-Fi/Bluetooth temperature/humidity sensor node.
- Select the MCU/module, likely an ultra-low-power ESP32-class module with Wi-Fi 2.4 GHz 802.11 b/g/n and BLE 5.x.
- Select a digital temperature/RH sensor, USB-C receptacle, 5 V input protection, current limiting, OVP/UVLO, and regulators.
- Build the schematic: USB-C 5 V default input, CC resistors, protection chain, power rails, MCU, sensor, programming/debug, boot/reset, and decoupling.
- Add consumer-use documentation: bring-up plan, firmware starter notes, and wireless/regulatory compliance notes.
- Then proceed to PCB placement/layout with antenna keepout, USB-C edge placement, power routing, and DRC/ERC verification.
