IoT Air Quality PCB Design
Budget: $30 – $250 USD
I have an air-quality monitor prototype on breadboard and now need a production-ready PCB. The core of the board will be an Arduino Nano, linked to Wi-Fi for cloud logging and OTA updates. Only a particulate-matter sensor has to be integrated at this stage, but I’d like the layout to leave space and headers so a future gas sensor can be dropped in without a full redesign.
What I expect from you:
• Complete schematic, PCB layout and clean routing for the Nano, Wi-Fi module, particulate sensor, regulated power path (USB-5 V input and Li-ion option), plus an on-board antenna or u.FL footprint.
• Clearly labelled break-outs for I²C, UART and an SPI port, and pads for an optional 0.96" OLED or similar display.
• All design files (KiCad or Altium), Gerbers, drill files, a fabrication drawing and an annotated, supplier-ready BOM.
• Brief design notes that explain component choices, antenna clearance, power-budget calculations and how to reconfigure the spare headers for future gas sensing.
Once I confirm the board boots, connects to Wi-Fi and streams raw particulate data over MQTT, the job is done. I’m happy to answer technical questions quickly so we can move from schematic to final Gerbers without unnecessary iterations.
