📱 Accelerometer
Measure acceleration in X, Y, and Z axes. Perfect for motion detection, orientation sensing, and physics experiments.
• X-axis: Left/Right tilt (roll) - changes when you tilt phone sideways
• Y-axis: Forward/Backward tilt (pitch) - changes when you tilt phone forward/back
• Z-axis: Up/Down + gravity (~9.8 m/s²) - changes with vertical movement
• Magnitude: Total acceleration combining all three axes
💡 Try this: Hold phone flat, then tilt it in different directions and watch the values change!
🎯 Gravity Measurement
Hold phone still and flat. Z-axis should read ~9.8 m/s² (Earth's gravity). Try in different orientations!
📐 Angle Measurement
Tilt phone to measure angles. Use X/Y values to calculate tilt angle: angle = arctan(√(x²+y²)/z)
⚡ Motion Detection
Watch magnitude change during movement. Higher values = more acceleration. Try walking, running, jumping!
🔄 Gyroscope
Track rotation around X, Y, and Z axes. Great for measuring angular velocity and rotational motion.
• X Rotation: Roll (left/right rotation around front-back axis)
• Y Rotation: Pitch (forward/backward rotation around left-right axis)
• Z Rotation: Yaw (left/right rotation around up-down axis)
• Units: Degrees per second (°/s) - how fast you're rotating
🎓 Physics Concept: Angular velocity measures how fast an object rotates around an axis.
🔊 Sound Level
Measure ambient sound levels using your device's microphone. Monitor noise levels in your environment.
• Sound Level: Decibels (dB) - logarithmic scale of sound intensity
• RMS: Root Mean Square - average amplitude of sound wave
• Reference Levels: Whisper (30 dB), Normal speech (60 dB), Traffic (80 dB), Rock concert (110 dB)
🎓 Physics Concept: Sound is a pressure wave. Decibels use a logarithmic scale because human hearing covers a huge range of intensities.
🧪 Chemistry Lab
