B4A Library PhoneSensorsExtra Library

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.

METHODS:
PhoneSensorsExtra
Version: 1
  • PhoneSensorsExtra
    Events:
    • sensorchanged (values() As Float)
    Fields:
    • TYPE_ACCELEROMETER As Int
    • TYPE_GRAVITY As Int
    • TYPE_GYROSCOPE As Int
    • TYPE_HUMIDTY As Int
    • TYPE_LIGHT As Int
    • TYPE_MAGNETIC_FIELD As Int
    • TYPE_MOTION As Int
    • TYPE_ORIENTATION As Int
    • TYPE_PRESSURE As Int
    • TYPE_PROXIMITY As Int
    • TYPE_STEP_COUNTER As Int
    • TYPE_STEP_DETECTOR As Int
    • TYPE_TEMPERATURE As Int
    Methods:
    • 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
    Permissions:
    • 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.


Enjoy!

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.

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

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
or
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

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;

Any ideas how I can access these sensors?

Thanks,

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 ?
