Knee Angle Goniometer Kit with Arduino Nano: Build a Wearable Joint Monitor for Physiotherapy

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

During knee rehabilitation, precisely tracking flexion angle is essential for safe progress. With this kit, you'll build a wearable device that straps to your leg and displays the bend angle instantly on an OLED screen-using an Arduino Nano and MPU6050 accelerometer-gyroscope. It's a practical tool for students, makers, and anyone serious about monitored physiotherapy.

What You'll Build

A functioning goniometer worn on the knee, capable of measuring angles from 0� to 180� in real time. The bright OLED shows the current angle, while a microSD module logs every reading with a timestamp from the DS3231 RTC. After a rehab session, you can review the data to track improvement or share it with a physiotherapist.

What You'll Learn

• Interfacing MPU6050 IMU sensor to extract pitch/roll for joint angle calculation
• Programming Arduino Nano for real-time sensor data processing and OLED display
• Integrating a DS3231 RTC for accurate time-stamping of measurements
• Storing sensor data on a microSD module for post-exercise analysis
• Designing a wearable circuit on a breadboard with practical 9V battery power management
