The PhyPhox app is free to install on both Apple and Android devices. While some devices may not have the same sensors, the function of PhyPhox is the same.
Coordinate System
Coordinate System
Many sensors in your phone depend on the orientation of the phone, like the inclinometer, accelerometer, and gyroscope. Coordinate axes associated with the phone are shown here. The z-axis is oriented normal to the phone's screen and the x and y axes are oriented to the right and up as one views the phone.
PhyPhox "Experiments"
PhyPhox "Experiments"
Phyphox calls each of the sensor measurement options an "experiment." It organizes the raw sensor and other experiments into categories:
Raw sensors: accelerometer, gyroscope, light, location, magnetometer, pressure
Acoustics: audio amplitude, autocorrelation, scope, spectrum, doppler, frequency history, sonar, tone generator
Camera: brightness, color, depth sensor (LiDAR)
Everyday Life: applause meter, elevator
Mechanics: collision, centripetal acceleration, pendulum, rolling velocity, spring frequency/period
Timers: acoustic, motion, optical, and proximity stopwatches
Tools: acceleration spectrum, inclination, magnetic ruler, magnetic spectrum
Many of these tools are further described on the Measurement pages on this site.
Controls
Controls
Each experiment has
A play/pause button to start and pause measurement
A delete button to clear collected data
A three-dots button to
access experiment info
export data
share a screenshot
perform a timed run
enable and disable remote access
save the experiment state and settings for easy access
The experiment may also have menus like
Settings - to change sampling rates
Graph - to view plotted data
Simple - to view a single-value representation of the value of a sensor
Multi - to view multiple values from a sensor
Trigger - to set trigger events and levels
And many more, depending on the sensor
Data viewing and Analysis
Data viewing and Analysis
The graphical analysis tools in PhyPhox are awesome!
Pan and zoom allows the user to pinch, pan, and zoom within a graph to focus on a particular set of data.
Pick data allows the user to select a single data point or quickly determine differences or slopes between two data points.
Select a single data point to view values.
Click and drag between data points to quickly see differences between x and y-axis data and the slope between two points.
Remote Control
Remote Control
One of the most helpful tools PhyPhox provides is the remote control option, which allows the user to place the phone into an experimental setup where its screen is not accessible and control the experiment through a web browser. This is described at https://phyphox.org/remote-control/.
