The smartphone's microphone enables several types of acoustic measurements:
Sound level meter: Measures the sound level in decibels (0-110 dB)
Dominant frequency: Identifies the main frequency (50-10000 Hz). Ideal for tuning an instrument.
Amplitude (oscilloscope): Displays the waveform of the audio signal in real time
Spectrograph: Shows the frequency spectrum (FFT) to analyze harmonics
Example experiments: Measuring noise pollution, studying the human voice, comparing pure and complex sounds, identifying musical notes.

The accelerometer measures the accelerations the phone undergoes along 3 axes:
• X: Front-back
• Y: Left-right
• Z: Up-down
Available modes:
• Linear: Without gravity (0 at rest)
• With gravity: Includes g (≈9.81 m/s² vertically at rest)
• Absolute: In the Earth's reference frame (independent of orientation)
Examples: Free fall, pendulum oscillations, studying motion in an elevator.

GPS provides several measurements:
• Latitude: North-south position (-90° to +90°)
• Longitude: East-west position (-180° to +180°)
• Altitude: Height above sea level (m)
• GPS speed: Travel speed (m/s or km/h)
• Accuracy: Position uncertainty (m)
Examples: Tracing a hike, measuring the speed of a vehicle, studying altitude changes.
Note: Turn on location in your phone's settings and allow FizziQ to access it.
