@Mahihassi

As an experienced and versatile Electrical Engineer with a dedicated focus on Embedded Systems, I bring forth the ideal skillset to complete your IoT Air Quality PCB Design project. Having worked extensively on projects similar to yours, my core expertise lies in microcontrollers and embedded systems such as Arduino- the very platform you'll require for your PCB design. Throughout my career, I've developed not only robust hardware but also complementing firmware that encompasses peripheral drivers, wireless stacks (BLE, Wi-Fi, LoRa, Zigbee), even AI through Machine learning or Deep learning algorithms. In terms of PCB design and RF hardware, I am highly skilled with various tools like Altium Designer, KiCad, Eagle, EasyEDA and Target. This extends to specialties like RF design which is vital for ensuring efficient performance of your anticipated Wi-Fi module and antenna layout. My experience will guarantee that we leave the provision for seamless upgrades such as dropping in a gas sensor in the future without a full redesign while maintaining a clean aesthetic.

Hello, I can convert your existing breadboard air-quality monitor into a production-ready PCB with a clean layout and room for future expansion. The board will be based on an Arduino Nano, include Wi-Fi connectivity for cloud logging and OTA updates, and integrate a particulate-matter sensor. The layout will intentionally reserve space and headers so a future gas sensor can be added without a full redesign. Scope includes: • Complete schematic and PCB layout • Power regulation for USB 5 V input with optional Li-ion support • Wi-Fi module integration with on-board antenna footprint • Clearly labeled I²C, UART, and SPI breakouts Deliverables: • KiCad or Altium design files • Gerbers and drill files • Fabrication drawing • Annotated, supplier-ready BOM • Brief design notes covering power, antenna layout, and future expansion options The project will be complete once the board powers up, connects to Wi-Fi, and streams particulate data over MQTT. I’m responsive to technical questions and can move efficiently from schematic to final Gerbers. Looking forward to working together. Regards Haseeb

✅✅✅ IoT PCB Design & Embedded Hardware Engineer ✅✅✅ Hi there, I have experience turning breadboard IoT prototypes into production-ready PCBs, including Arduino Nano–based designs with Wi-Fi, sensors, and OTA-ready power architectures. I’ve delivered compact, well-documented boards used for cloud-connected monitoring and data logging. My approach is to design a clean schematic and efficient PCB layout with proper power regulation, antenna clearance, and expandability in mind. I’ll integrate the particulate sensor, Wi-Fi module, and breakout headers while reserving space and interfaces for future gas sensors without redesign. A few questions: Which Wi-Fi module do you prefer (ESP8266/ESP32)? Any enclosure size constraints? Do you want USB and Li-ion power selectable automatically or via jumper? I am ready to start immediately. Best regards

@djalltra

Hi,after going through the project description here's my approach The core design will center on a socket for your Arduino Nano. Power will be flexible, accepting both USB-C and a Li-ion cell via a TP4056 charger circuit. Connectivity is handled by an ESP-12F Wi-Fi module for cloud functions and OTA updates. Your PMS5003 sensor gets a dedicated port. Right beside it, I'll place an identical expansion header that breaks out the Nano's spare I²C, UART, and SPI lines, plus power rails. This creates a direct plug-and-play port for a future gas sensor. A separate 4-pin header will be included for an optional I²C OLED. You'll receive the complete KiCad project files, manufacturing-ready Gerbers and drill files, a fabrication drawing, and a sourced BOM. I'll also provide brief design notes covering component rationale, antenna keep-out guidance, basic power calculations, and instructions for reconfiguring the expansion header. Thanks

I have just completed a similar project. I recently developed a production-ready PCB integrating an Arduino Nano with Wi-Fi connectivity to stream environmental sensor data via MQTT seamlessly. You won’t find a specialist better aligned with what you’re looking for. I understand the importance of delivering a clean, modular PCB layout that supports current sensor integration and future expansions without a complete redesign. I specialize in transforming complex business requirements into high-converting, user-centric digital assets. I’d love to chat about your project!
