Useful for students and teachers in science, technology, engineering, and math (STEM) education and academic or industrial researchers, this app uses device sensor inputs to collect, record, and export data in comma separated value (csv) format through a shareable .csv file. Data can be plotted against elapsed time on a graph or displayed digitally. Users can export the data for further analysis in a spreadsheet or plotting tool. This app also generates tones, colors, and a stroboscope. See www.vieyrasoftware.net for a variety of usage ideas for STEM education and publications from academia and industry.A menu allows the user to sense or generate the following (dependent upon the user’s mobile device capabilities):SENSORS(1) G-Force Meter - ratio of Fn/Fg (x, y, z and/or total)(2) Linear Accelerometer – acceleration (x, y, and/or z)(3) Gyroscope - radial velocity (x, y, and/or z)(4) Barometer - atmospheric pressure (5) Roller Coaster - G-Force Meter, Linear Accelerometer, Gyroscope, and Barometer(6) Hygrometer - relative humidity(7) Thermometer - temperature(8) Proximeter - periodic motion and timer (timer and pendulum modes)(9) Ruler - distance between two points(10) Magnetometer - magnetic field intensity (x, y, z and/or total)(11) Compass - magnetic field direction and bubble level(12) GPS - latitude, longitude, altitude, speed, direction, number of satellites(13) Inclinometer - azimuth, roll, pitch(14) Light Meter - light intensity(15) Color Detector - detects HEX colors within a small rectangle area on the screen via the camera.(16) Sound Meter - sound intensity(17) Tone Detector - frequency and musical tone(18) Oscilloscope (audio) - wave shape and relative amplitude(19) Spectrum Analyzer (audio) - graphical FFT(20) Spectrogram (audio) - waterfall FFTMULTI RECORD(21) Multi Record - choose one or more of the above sensors to collect data at the same time.GENERATORS(22) Tone Generator – sound frequency producer(23) Color Generator – R/G/B/Y/C/M, white, and custom color screen(24) Stroboscope (beta) - camera flash(25) Play - challenges(26) Manual Data Plot Features(a) Recording: All sensor data can be recorded by pressing the red floating action button. Saved data can be found stored in the folder icon and on the device’s SD card.(b) Exporting: Data can be immediately transferred following recording by selection an option to send via e-mail or shared in Google Drive or Dropbox. Locally saved files can also be transferred from the folder icon.(c) Sensor Information: Clicking on the (i) icon within each mode provides information about the sensor name, vendor, and current data collection rate, in addition to a description of what kind of data is collected by the sensor, its physical operating principle, and links to additional resources, including webpages and videos that illustrate how it works. Settings* Note that not all settings are available for all sensors.(a) Data Display: View data in graphical, digital, or vector form.(b) Graph Display: View multi-dimensional data sets on a single shared graph or in multiple individual graphs.(c) Displayed Axis: For multi-dimensional data on a single shared graph, select total, x, y, and/or z-axis data. (d) CSV Timestamp Format: Record clock time or elapsed time with sensor data.(e) Line Width: Modify visual presentation of data with a Thin, Medium, or Thick line.(f) Sensor Collection Rate: Set collection rate as Fastest, Game, UI, or Normal. The sensor collection rate is displayed for each option when selected.(g) Keep the Screen On: Prevent the app from turning the screen off automatically.(h) Calibrate: Calibrate selected sensors.Permissions Explained:LocationUsed to calculate the azimuth.Photos/Media/FilesA csv file is created and modified on the phone´s internal memory.MicrophoneThe app has a sound meter mode that analyzes sound using the microphone.

La meva bio
Sóc físic i enginyer informàtic. Professor de física i química i entusiasta del mètode experimental; tanmateix m'agrada programar i construir/maquetar. Intento inocular aquestes passions al meus estudiants. Aficionat a l'observació astronòmica; també miro de trobar temps per córrer, nedar i practicar mountainbike.
Did you know that you are carrying a 3D magnetometer? That you can use your phone as a pendulum to measure earth´s local gravitational acceleration? That you can turn your phone into a sonar?phyphox gives you access to the sensors of your phone either directly or through ready-to-play experiments which analyze your data and let you export raw data along with the results for further analysis. You can even define your own experiments on phyphox.org and share them with colleagues, students and friends.Selected Features:- A selection of pre-defined experiments. Just press play to start.- Export your data to a range of widely used formats- Remote-control your experiment through a web interface from any PC on the same network as your phone. No need to install anything on those PCs - all you need is a modern web browser.- Define your own experiments by selecting sensor inputs, defining analysis steps and creating views as an interface using our web-editor (http://phyphox.org/editor). The analysis can consists of just adding two values or using advanced methods like Fourier transforms and crosscorrelation. We offer a whole toolbox of analysis functions.Sensors supported:- Accelerometer- Magnetometer- Gyroscope- Light intensity- Pressure- Microphone- Proximity- GPS*some sensors are not present on every phone.Export formats- CSV (Comma separated values)- CSV (Tab-separated values)- Excel(if you need other formats, please let us know)This app has been developed at the 2nd Institute of Physics A at the RWTH Aachen University.--Explanation for the permissions requestedIf you have Android 6.0 or newer, some permissions will only be asked for when needed.Internet: This grants phyphox network access, which is required to load experiments from online ressources or when using the remote access. Both are only done when requested by the user and no other data is transmitted.Bluetooth: Used to access external sensors.Read external storage: This is may be neccessary when opening an experiment stored on the device.Record audio: Required to use the microphone in experiments.Location: Used to access GPS for location-based experiments
