Arduino Lung Capacity Breath Meter Kit – Compare Peak Breath Pressure Across Age Groups

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

With this kit, you’ll assemble a device that measures how hard you can blow into a tube and displays your peak breath pressure on an LCD. It’s a fun, hands-on way to explore respiratory physiology and compare lung capacity between classmates, siblings, or age groups. Perfect for science fairs and CBSE investigatory projects.

What You'll Build

You’ll build a complete breath meter that captures the maximum air pressure from a single blow using an MPX5010 differential pressure sensor connected to a tube. The Arduino Uno processes the signal and displays the peak value on a 16x2 LCD in real time. You can use it to run experiments comparing lung strength across different ages and physical activities.

What You'll Learn

• How to interface an analog pressure sensor with Arduino
• Reading sensor voltage and converting it to pressure units
• Programming peak detection to capture highest breath pressure
• Displaying real-time sensor data on a 16x2 LCD using I2C

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for school students from Class 5 upwards exploring human biology through electronics. It’s ideal for CBSE Class 11-12 investigatory projects in biology or physics, ATL Tinkering Lab activities, and science fair entries. Even young makers at home can build it with minimal supervision.

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.
