Sport Bottle Pressure Monitor Kit — Build a Real-Time Flow & Pressure Logger with ESP32

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Build a purpose-engineered device that reads fluid pressure and flow rates using the MPX5010 and YF-S201 sensors, logs the data to an SD card with precise timestamps from the DS3231 RTC, and controls an external solenoid valve via relay—perfect for monitoring a home oxygen concentrator or a high-performance sports hydration bottle. This kit transforms a messy breadboard prototype into a clinical-grade tool for health tech applications.

What You'll Build

You'll assemble a stable, enclosure-mounted monitoring station that continuously tracks O2 flow or water pressure. The 0.96-inch OLED displays real-time readings, while the microSD module captures logs for later analysis. With the relay module, you can autonomously cut off flow when pressure deviates beyond safe thresholds—a critical feature if you are adapting existing oxygen therapy equipment for sports recovery or altitude training. The entire system runs off a 12V adapter with a buck converter for clean power.

What You'll Learn

• Interfacing the MPX5010 differential pressure sensor with the ESP32's ADC and mapping raw values to kPa
• Reading pulse output from the YF-S201 hall-effect flow sensor and calculating litres per minute
• Logging timestamped sensor data to a MicroSD card using SPI communication
• Controlling an external solenoid valve through a relay based on real-time pressure thresholds

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is built for B.Tech and M.Tech students in ECE or biomedical engineering who are prototyping Smart India Hackathon ideas around affordable healthcare devices. It also suits health-tech startup engineers and research scholars at IIT, NIT, or BITS campuses developing point-of-care monitoring tools. If you're a maker over 25 building a home oxygen concentrator or a sports recovery setup with precise pressure control, you'll bypass months of sourcing and debugging.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
