Hi, We reviewed your requirements and this project is a great match for our experience in embedded systems, sensor interfacing, and PCB design. We can design a complete oxygen analyzer around the Southland Sensing PO2-1x sensor, including the analog signal conditioning, microcontroller interface, firmware, and a production-ready PCB. The design will focus on accurate low-current signal measurement, stable operation, and ease of calibration. Please visit our profile and portfolio to review our previous embedded hardware and sensor interface projects. Timeline: 6 Days Budget: ₹6,000 (We can discuss the budget further based on the final scope.) A few questions: Do you require a display, or will the readings be transmitted digitally? What supply voltage will the analyzer use? Do you already have calibration gas and calibration requirements? We are available to start immediately and will provide regular progress updates. Regards, M&C Eng

With my extensive experience as an Embedded Systems Developer and IoT Engineer, I am confident in my ability to deliver a reliable and efficient Oxygen Analyser using the sensor specified. My background involves working with STM32, ESP32, ESP8266, ATmega, Arduino, Raspberry Pi – among other technologies – which are directly relevant to this project. Not only can I integrate sensors into hardware effectively, but I am also highly skilled at hardware interfacing. Having worked on devices like CNC machines and 3D printers, I am well-versed in Marlin firmware and ensure optimal performance in these systems. My proficiency extends to various communication protocols including BLE, LoRa, USB, RS232, I2C and SIM800L – skills that would be vital for an Oxygen Analyser project. To complement my hardware skill set is my proficiency in Python development, essential for backend system development and API integration for device-to-server communication. Being also adept in Linux Server Administration would allow me to effectively manage the resulting system's servers. As we go through this process, trust me to prioritize quality, stability, and performance for the most practical and effective outcomes possible.

Hello, I can device a suitable measuring circuit to convert the current output to voltage and read by a microcontroller/Arduino and send to computer for display on a small LCD display for the device. Please let me know what exactly you mean to analyze beyond showing the percentage. If you want a pcb to be done or do you need box etc?

Hello, I have experience in embedded systems, analog signal conditioning, PCB design, and sensor interfacing. I can develop an oxygen analyzer around the PO2-1x sensor, including the analog front-end, microcontroller firmware, display, calibration, and PCB if required. Quick question: Do you need only the embedded electronics/PCB, or are you also expecting a complete analyzer with display, enclosure, and calibration software? I can start immediately once the requirements are confirmed

Hello, I’m interested in assisting with your oxygen analyzer development. I have hands-on experience in Embedded Systems, sensor interfacing, microcontroller programming (Arduino, ESP32, STM32), PCB design, and hardware integration. I’m comfortable working directly from sensor datasheets to design reliable measurement systems. For this project, I can: Study the provided oxygen sensor datasheet and determine the required interface circuitry. Design the signal conditioning and sensor interface. Develop the embedded firmware for accurate oxygen concentration measurement. Assist with calibration, testing, and hardware validation. Provide clear documentation and support until the system is working as expected. I focus on building reliable, well-documented solutions and maintain regular communication throughout the project. Looking forward to working with you. Mahesh Dumpa

Hello, I am a PhD graduate in Sensor Technology with over 6 years of experience in embedded systems, sensor interfacing, STM32 firmware development, and custom PCB design. Your oxygen analyzer project closely matches my expertise. My doctoral research involved developing precision gas sensing systems, real-time sensor data acquisition, calibration algorithms, and embedded instrumentation. I have extensive experience designing embedded hardware and firmware for sensor-based measurement systems. I can assist with: • Sensor interface circuit design • STM32/Arduino firmware development • Signal conditioning and calibration • Real-time oxygen concentration measurement • PCB design (if required) • Testing and documentation I reviewed the attached PO2-1x oxygen sensor specification and understand its analog microamp output and calibration requirements. Before starting, I'd like to know: • Which microcontroller do you prefer? • Do you need only firmware or complete hardware development? • Is a display or PC interface required? I look forward to discussing your project. Best regards, Dr. Satyendra Vishwakarma
