I’m building an embedded IoT device intended for industrial control environments and need an experienced developer who can take it from concept to working prototype. Scope The core of the project is a reliable, low-power embedded platform that can sit on the factory floor, read multiple sensor inputs, and talk securely to a cloud or on-premise server. Robustness, easy field-upgrades, and tight integration between hardware and firmware are critical. Required capabilities • Remote monitoring and control • Data collection and analytics • Predictive maintenance What I expect as deliverables 1. Schematics, BOM, and PCB layout files for the hardware. 2. Production-ready firmware (C/C++ or an RTOS) with documented APIs, OTA update hooks, and secure network stack (MQTT, TLS, or equivalent). 3. A simple web or mobile dashboard mock-up that visualises live data and allows basic control commands, just to prove end-to-end connectivity. 4. Step-by-step build and deployment instructions so my in-house team can replicate the setup. Acceptance criteria • Stable communication over at least one industrial fieldbus or Ethernet/Wi-Fi interface. • Sensor data reaches the dashboard with <2 s latency under normal load. • Firmware compiles without warnings and passes a 48-hour continuous stress test. • Complete project folder handed over in an organised, buildable state. If this matches your skill set in embedded C, PCB design tools such as KiCad / Altium, and cloud integration (AWS IoT, Azure IoT Hub, or similar), I’m ready to get started right away.

Hi, I can help develop your industrial IoT control device from concept to working prototype, including hardware design, firmware, secure communication, OTA-ready architecture, and a simple dashboard proof of connectivity. The best solution is to first confirm sensor types, control outputs, power limits, fieldbus/Ethernet/Wi-Fi requirements, enclosure constraints, cloud/on-premise target, and environmental conditions. Then I can design the schematic, BOM, and PCB layout, develop firmware in C/C++ or RTOS, implement secure MQTT/TLS communication, add OTA update hooks, and create a basic dashboard to show live data and control commands. I’m comfortable with embedded C/C++, microcontrollers, RTOS, KiCad/Altium PCB design, sensor interfaces, industrial communication, MQTT, TLS, OTA updates, AWS IoT/Azure IoT-style integration, firmware APIs, stress testing, and end-to-end prototype documentation. Deliverables will include: * Schematics and BOM * PCB layout files * Production-ready firmware * Secure network stack * OTA update structure * Sensor data collection * Remote monitoring/control APIs * Dashboard mock-up * Build/deployment guide * Organized source/project folder I’ll focus on reliability, low-power operation, clean hardware-firmware integration, stable communication, and a prototype your in-house team can reproduce and extend.

I'm a specialist in embedded electronics and IoT systems with 13+ patents in the field. This project aligns perfectly with my experience: I've built wireless telemetry platforms (SailSensor) and industrial gateways integrating multiple sensors with cloud/on-premise servers over MQTT and secure protocols. I can deliver end-to-end: • Hardware: schematics, KiCad layout, BOM with industrial-grade components and power optimisation • Firmware: bare-metal C/C++ or Zephyr RTOS on Nordic/STM32, with OTA bootloader, TLS stack, and sensor drivers • Dashboard: proof-of-concept web UI showing live data and control commands • Documentation: build guide, API specs, and stress-test logs I focus on robustness—tight hardware/firmware integration, field-upgradable architecture, and <2s latency over industrial fieldbus (CAN, RS485) or WiFi. All code compiles clean, zero warnings. Ready to start immediately. Let's discuss microcontroller choice and fieldbus preference. Which industrial fieldbus or interface is priority for your deployment (CAN, RS485, Ethernet, WiFi)? Will you use AWS IoT, Azure, or a custom on-premise MQTT server?

Straight to it. I design and manufacture a steel frame FDM 3D printer that runs on my own 4 layer STM32 controller board, laid out in KiCad, with firmware in embedded C. It is in production and sold to customers, so I have taken a multi sensor, closed loop control device from schematic to BOM to PCB to field deployment and support. That is the exact arc you are describing. Where I am strongest: PCB design in KiCad, embedded C on STM32, sensor integration, thermal and motion control, and control systems generally (my background is Electrical Power and Control Engineering with PLC and SCADA). I also build my own web dashboards for QA and stress testing, so the end to end data path and your 48 hour stress test are familiar ground, not new territory. On the cloud side I build the secure path as a defined milestone: MQTT over TLS, OTA update hooks, and a live dashboard, on AWS IoT or whichever broker you prefer. My existing firmware and dashboards already handle local telemetry, so wiring that to a broker is the next layer, not a leap. I would rather scope that cleanly than oversell it. Before I quote firm, can we lock a few things on a quick call: sensor types and count, control outputs, power budget, and whether this is Wi Fi, Ethernet, or an industrial fieldbus. I can share board photos and files on request. Fadl

I'm an embedded systems engineer specializing in multi-node ESP32 IoT systems, and this project matches work I've shipped. Most relevant: LUMA, a two-node system (Hub + Pole) where the Hub bridges a PHP server over HTTP while running ESP-NOW concurrently on the same radio — not time-sliced. This meant solving real-time problems close to yours: decoupling interrupt-driven wireless callbacks from blocking network calls (built a flag-based pattern for it), stable multi-sensor ADC sampling (PIR, LDR, battery voltage), and auto-timeout/ack logic for field reliability. I've also built multi-node ESP32 systems reporting to a PHP/MySQL dashboard, solving WiFi channel coexistence issues — directly relevant to your dashboard latency requirement. My approach: Hardware: Schematics, BOM, PCB layout (KiCad), low-power design Firmware: C/C++ or RTOS, MQTT+TLS, OTA hooks, documented APIs Dashboard: Lightweight web UI for live data + control commands Handover: Organized files, build/deployment docs for your team One honest gap: less production experience with industrial fieldbus (Modbus/RS-485) and inductive-load power electronics. I'd scope time to solidify these rather than guess, or we can discuss a specialist for that piece. Happy to start with a short call to lock down sensor count, fieldbus needs, and cloud provider before quoting a fixed timeline.
