Monitor Asthma with a DIY Peak Flow Logger Using Arduino Nano

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

Take control of respiratory health by building a peak flow meter that logs readings over time. This kit helps you track lung function trends, an essential tool for asthma management and early warning. Whether for personal use or a CBSE science project, you'll create a portable logger with a real-time OLED display.

What You'll Build

You'll assemble a handheld device that measures peak expiratory flow using a differential pressure sensor. After a forced exhale, the Arduino Nano processes the airflow and displays the PEF value on the OLED screen, while automatically saving a timestamped reading to a microSD card. All components fit compactly on a breadboard.

What You'll Learn

• Interfacing an MPX5010 differential pressure sensor with Arduino for medical-grade airflow measurement.
• Implementing a real-time clock (DS3231) for accurate time-stamping of health data.
• Writing data to a microSD card in CSV format for later analysis in Excel or Google Sheets.
• Displaying live sensor readings and system status on a 0.96-inch OLED screen.
