light sensor

[Cor]

This code will not show up the lightevent

Am I missing something?

Dim pSensor As PhoneSensors

 pSensor.Initialize(psensor.TYPE_LIGHT)   
  Log(pSensor.MaxValue)
  If pSensor.StartListening("LightEvent")= True Then
    Log("light sensor supported")
  End If

Sub LightEvent
 Log(pSensor.MaxValue)
End Sub

Sub LightEvent_SensorChanged (Values() As Float)
...
End Sub

thanks,

but i could not find this information in the documentation

can you show me where i can find it

The event and its parameter list are in the documentation of PhoneSensors here Basic4android - Phone and also in the help viewer.

There is an example using the event in the first post here http://www.b4x.com/forum/additional...pdates/7723-phone-library-update-v1-32-a.html

light sensor is working but giving only 75 lux and 210 lux

seems on/off values


when just there is a little light into the sensor it goes to 75 lux


Test with other sensor apps are getting more values between 75 and 210

using huawei s7 latest capacitive version

Could it be that some phones only report a level switch
below or above which the flash is or is not needed...?

Hello

I want the actial light status of my room
so I made

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
Dim pSensor As PhoneSensors

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
pSensor.Initialize(pSensor.TYPE_LIGHT)
  Log(pSensor.MaxValue)
  If pSensor.StartListening("LightEvent")= True Then
    Log("light sensor supported")
End If

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub LightEvent
Log(pSensor.MaxValue)
End Sub
Sub LightEvent_SensorChanged (Values() As Float)
    Log (Values)
End Sub

But when i add Log (Values) my program stopps
What i want is get the actual light in real time

Installing file.
