Develop BLE Pressure Sensor System with nRF52840 DK for Mobile App (Low Power) (electronic engineer)

I'm seeking a skilled embedded developer experienced with the Nordic Semiconductor nRF52840 DK to design and implement a pressure sensor system. This system will: Utilize 8 pressure sensors (your preferred models with 0-2 bar or 0-30 psi gauge pressure range) suitable for the nRF52840 DK. Continuously collect pressure data from the sensors with low power consumption for extended battery life. Communicate pressure data wirelessly to a smartphone application via Bluetooth Low Energy (BLE). Allow for configuration and interaction with the pressure sensors through the mobile app (optional). Key Requirements: Expertise in nRF52840 DK development, including sensor interfacing, BLE communication, and low-power programming. Strong understanding of pressure sensor selection and integration for accurate and reliable pressure readings. Experience with mobile app development for BLE communication (Android or iOS) is a plus. Familiarity with power optimization techniques for extended battery life in embedded systems. Excellent communication and collaboration skills. Deliverables: Fully functional pressure sensor system using the nRF52840 DK and chosen pressure sensors. Well-documented source code for the nRF52840 DK firmware. (Optional) Mobile app for pressure data visualization and control (if applicable). Budget: Please specify your competitive budget range for this project. Timeline: Outline a realistic timeline for project completion, considering the complexity of sensor selection, app development (if included), and integration. Additional Information: Briefly describe the intended application of the pressure sensor system (e.g., industrial monitoring, fitness tracker, etc.). Mention any specific preferences you have for pressure sensor models or mobile app features (if applicable). By providing these details, you'll attract qualified freelancers who understand the nRF52840 DK, BLE development, and low-power considerations. You'll also give them a clear understanding of your project goals and expectations. Tips for Success: Post your project on reputable freelancer platforms with a focus on embedded systems and mobile app development. Carefully review freelancer profiles and portfolios to ensure they have the necessary experience with the nRF52840 DK and BLE development. Clearly communicate your project requirements and budget in the initial post.
