for a natural swimming pool with 2 pools I build the following:
2 Sender where each read 2 sensor and deliver the current values it via lora
1 receiver, which can ask for history data via phyphox.
I wish to create a rangefilte that filter incorrect data (e.g. -127 °C)
If i build the phybox file without rangefilter, the app displays the correct raw data.
with rangefilter it displays only the batteryvoltage, which is not filterd

so any idea, whats the problem?

has anyone ever tried to use phyphox as a simple oscilloscope for external electrical signals?

I could imagine two possibilities:
  • Using the phone's microphone or audio input and connecting an
    external signal through a suitable protection circuit.
  • Using something like an Arduino or ESP32 to measure the signal
    and send the values to phyphox.

I’m mainly interested in whether this works well enough for simple experiments,
for example with sine waves, square waves, resistor-capacitor circuits, oscillators or induction.

For the microcontroller version, I’m also wondering how fast values can be sent to phyphox and
whether it would be possible to collect some first and then send them together.

Has anyone tried something similar or has an ideas?

Thanks you for any ideas or experiences!]]>

ich habe ein Problem beim Zusammenführen von zwei Messgeräten.
Der Laborino (BLE) soll die magnetische Flussdichte in der Nähe eines geraden stromdurchflossenen Leiters messen, während man am Netzgerät die Stromstärke erhöht welche vom OWON-Mutimeter (BLE) gememessen wird und ebenfalls an phyphox die Daten sendet.

Die beiden Größen welche ich in einem Diagramm gegenüberstellen will, kommen demnach von zwei verschiedenen BLE Geräten (Laborino und OWON-Multimeter). So wie ich das verstehe ist mein Problem, dass der zeitliche Zusammenhang der Größen nicht da ist und somit kein sinnvolles Diagramm entstehen kann (z.B in einem Container sind 100 Werte während im anderen bereits 1000 sind) Um das zu lösen habe ich bereits mit dedizierten Containern nur für die Diagrammerstellung herumgespielt. z.B um immer dann den letzten Magnetfeldwert zu lesen, wenn ein neuer Strom- bzw Zeitmessung vom OWON hereinkommt (d/dt größer null). Diese Werte (Container Größe 1) werden in einen Container (Größe 0) angehangen. Und auch der aktuelle Magnetfeldwert soll dann in einen eigenen Container ((MAG_sing) für Single) gespeichert werden. Dieser wird dann an den eigenen Container Größe 0 angehangen.

Da es ein eigenes Laborion Experiment ist, wird es nicht bei euch wahrscheinlich nicht Laufen, aber vielleicht hilft der Code schon weiter.

Es müsste sich mit dem OWON Multimeter und dem Smarphone Magnetometer nachstellen lassen.

Kann man die Schwingungen einer Fußgängerbrücke mit Phyphox messen und analysieren? Ich frage mich ob das möglich ist indem man auf die Brücke springt und die Schwingungen so aufzeichnet. Beeinflusst die Bewegung des Telefons in der Hand möglicherweise die Messung?

Wenn es geht, wie findet man die Resonanz/ Grund frequenzen. Benötige ich dafür beispielsweise Python, oder ist die Analyse direkt in der App möglich? Danke für ihre Antwort!]]>
Kann man die Schwingungen einer Fußgängerbrücke mit Phyphox messen und analysieren? Ich frage mich ob das möglich ist indem man auf die Brücke springt und die Schwingungen so aufzeichnet. Beeinflusst die Bewegung des Telefons in der Hand möglicherweise die Messung?

Wenn es geht, wie findet man die Resonanz/ Grund frequenzen. Benötige ich dafür beispielsweise Python, oder ist die Analyse direkt in der App möglich?

I was wondering whether the tilt of the phone influences the measurements in the z direction. In other words, should I correct the values by the cos of the tilt angle?

Thank you.

Since I want to limit the sampling rate to another number, I changed a bit in the code.
- <input>
    <sensor type="accelerometer" rate="0">  # I changed to 50 and 80

I succeeded in loading the experiment to my phone already.
However, there were some strange things:
- For the 50Hz case: Sometimes the sampling rate starts at 33Hz and then slowly reaching 45 Hz and fluctuates; sometimes it starts perfectly at 50Hz and does not change at all
- For the 80Hz case: The sampling rate is always at 50Hz

I would really appreciate it if you could let me know what the reasons might be.
And maybe a way to fix?

I am having a problem in terms of loading a .phyphox file into the app.
My purpose for doing this is to limit the accelerometer's sampling rate to 50Hz.

1) I originally took the code from https://github.com/phyphox/phyphox-exper...um.phyphox
Then I changed <phyphox version="1.7" locale="en"> to  <phyphox version="1.2.0" locale="en"> so as to match the current version of Phyphox on my phone; and <sensor type="accelerometer" rate="0"> to  <sensor type="accelerometer" rate="50">

When I loaded this experiment onto Google Drive and logged in phyphox://[URL], the error shows as
''exp_error
Could not load experiment: Invalid experiment file. Unkown file format.''
I would really appreciate if you guys could show me where I could have gone wrong in my practice.

2) I managed to add the experiment to Phyphox by sending through email and opening directly with Phyphox.
However, there is a function missing in Github version compared to the version from AppStore,
which is the Peak Frequency (Hz) - Time graph in the History section (you can see in my attachment below.
Where should I find the code for the missing part?

Thank you so much for your time!

More specifically, I was curious if it would be possible to use uploaded data to analyze things such as barometric pressure changes from an event like a gunshot or other impulse-type event, rather than only using live sensor data collected directly from the phone.
I know Phyphox can record pressure sensor data live from supported devices, but I was wondering if there is any capability for importing datasets afterward for review, graphing, or comparison.

Attempting to use the

Thought the error-message could be improved to suggest enabling Bluetooth.

Ich arbeite grade an meinem Bachelorprojekt und bräuchte euren Rat. Ich möchte ein Smartphone auf ein ferngesteuertes Auto befesteigen um die Fahrdynamik zu tracken und die Live-Daten in ein Web Dashboard zu übertragen.

Mein Ziel ist es, die JSON Daten aus dem Experiment "Beschleunigung ohne g" per Fernzugriff auf mein Tablet zu senden und Geschwindigkeit, Brems und Kurvenverhalten in einem selbstgebauten Dashboard mit Balken anzuzeigen. Das HTML Gerüst ist fertig und ich hab es mit der Java Script "fetch" Funktion probiert, aber es funktioniert noch nicht. Könnt ihr mir da eventuell weiterhelfen? Oder wisst ihr zufällig, ob es für so ein Web-Dashboard schon fertige Code Beispiele gibt oder ob jemand aus der Community schon mal etwas Ähnliches umgesetzt hat?

New to the Android app, and not seeing a direct answer in general searching.

If I where to get a sensor that uses the usb interface and attach it to my phone will the app be able to detect and monitor the sensor? 

Is there a step between being to the sensors on the phone out of the box and building an esp sensor box and connecting to it via Bluetooth?

Ps.
Can experiments be set to run while the app is in the background and/or the screen is locked?]]>
