Analyse de l'application Physics Toolbox Sensor Suite P pour le 13 janvier

This app uses internal smartphone sensors to collect, display, record, and export .csv data files. See www.vieyrasoftware.net to (1) read about case usage in research and development, and (2) get lesson plans for educators of science, technology, engineering, and mathematics (STEM) fields, including physics. Sensor availability, precision, and accuracy are dependent upon smartphone hardware. Sensors, generators, and data analysis tools include the following: KINEMATICS G-Force Meter - ratio of Fn/Fg (x, y, z and/or total) Linear Accelerometer – acceleration (x, y, and/or z) Gyroscope - radial velocity (x, y, and/or z) Inclinometer - azimuth, roll, pitch Protractor - angle from vertical or horizontal ACOUSTICS Sound Meter - sound intensity Tone Detector - frequency and musical tone Tone Generator – sound frequency producer Oscilloscope - wave shape and relative amplitude Spectrum Analyzer - graphical FFT Spectrogram - waterfall FFT LIGHT Light Meter - light intensity Color Detector - detects HEX colors within a small rectangle area on the screen via the camera. Color Generator – R/G/B/Y/C/M, white, and custom color screen Proximeter - periodic motion and timer (timer and pendulum modes) Stroboscope (beta) - camera flash Wi-Fi - Wi-Fi signal strength MAGNETISM Compass - magnetic field direction and bubble level Magnetometer - magnetic field intensity (x, y, z and/or total) Magna-AR - augmented reality visualization of magnetic field vectors OTHER Barometer - atmospheric pressure Ruler - distance between two points GPS - latitude, longitude, altitude, speed, direction, number of satellites System Temperature - battery temperature COMBINATION Multi Record - choose one or more of the above sensors to collect data at the same time. Dual Sensor - display data from two sensors on a graph in real time. Roller Coaster - G-Force Meter, Linear Accelerometer, Gyroscope, and Barometer PLOTTING Manual Data Plot - enter data manually to generate a graph. GAME Play - challenges FEATURES (a) Record: Record by pressing the red floating action button. Find saved data stored in the folder icon. (b) Export: Export data by selecting 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 to identify sensor name, vendor, and current data collection rate, and to learn what kind of data is collected by the sensor, its physical operating principle, and links to additional resources. 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.
