    Hello all, i worked on an app for a client a while back and needed to retrieve a few extra information from the embedded sensors in the phones, I tried the PhoneSensors library that comes with B4A but did not provide me with the information i needed for this specific App. So I created my own, is very similar to the one that comes with B4A but with some extra stuff, hope someone finds it useful.

    • PhoneSensorsExtra
      • sensorchanged (values() As Float)
      • TYPE_GRAVITY As Int
      • TYPE_HUMIDTY As Int
      • TYPE_LIGHT As Int
      • TYPE_MOTION As Int
      • TYPE_PRESSURE As Int
      • Initialize (SensorType As Int)
      • Initialize2 (SensorType As Int, SensorDelay As Int)
      • StartListening (EventName As String) As Boolean
      • getAllSensors As List
      • getMaximumRange (info4 As Float) As Float
      • getName (info1 As String) As String
      • getPower (info2 As Float) As Float
      • getResolution (info3 As Float) As Float
      • getVendor (info As String) As String
      • getVersion (info5 As Int) As Int
      • android.permission.INTERNET

    I did not create an example apk for this since the library is very simple. Anyone should be able to use it by just looking at the methods.

    I wonder what "TYPE_HUMIDTY" does?, what I would really like is a HUMIDITY sensor, can you add that please? :D.

    Yes, I know. :p

    In that case I would have to change all the TYPES, You might have to ask Erel to change his too then :)

    But I will do it just for you NJ!

    You are the best!!

    Also, the Event doesn't look right, maybe a copy-paste glitch?

    Fixed it, is actually a glitch in the xml2bb thingy. LOL

    Good catch.

    Hey Walter, thanks for this library.

    One question: Why the Internet permission ?
    • android.permission.INTERNET

    Hi Walter, Is there any way to stop listening once started?

    Thanks.... Do you have the cycle time of the whole loop? Louis

    I'm not sure i understand your question!

    I mean the cycle time for reading the gyroscope / accelerometer / compass sensors and computing the Pitch / Roll / Yaw from these sensors ?

    Whats the type of a sensor?
    Dim imu_sensor As PhoneSensorsExtra
    Dim imu_sensor As PhoneSensors
    doesnt work:(

    Yep Agree, I need to count steps and it's not possible with this lib or at least there's not such a simple way to use it.

    Walter could you give us just a little clue?

    Thanks a lot

    Why the "Internet permission" ?

    Note that you can remove permissions with RemovePermission (in the manifest editor).

    Hi dudes,

    I'm using step detection, when walking starts, after some steps it returns value=1, this is all right. Any way to stop listening the sensor or detect not walking state ?

    Thanks in advance.

    listI am a total beginner on this app development thing, having put together a simple 1 screen app with some logic, calculations based on input and reading and writing to a database. However I really want to access Temperature, Humidity and Barometric Pressure sensors that I know are present in my S8+, but dont seem to be found by this library when I looped through the getAllSensors list. Of the 3 I want I could only find the following;

    {Sensor name="LPS22H Barometer Sensor", vendor="STMicroelectronics", version=1, type=6, maxRange=1260.0, resolution=2.4414062E-4, power=1.0, minDelay=100000}

    However I have no idea what code I need to write to read this sensor. Sorry, but I don't understand the concepts of methods, fields and events that is assumed in the original post.

    Any help on sample code would be much appreciated.

    When I run an app on my S8+ called Galaxy Sensors I get the following, which indicates the presence of working Barometric Pressure, Temperature and Humidity sensors;
    However when I parse all of the sensors using PhoneSensorsExtra library, I get the following, which has the Temperature and Humidity sensors missing;

    without sample code, the library seem to be useless for some people like me...
    moreover, for magnetic field sensor, the output is in what unit ? Gauss or Tesla or ? and how to combine the Value(0), Value(1) and Value(2) to get the final reading ?
