Hi there, I've just discovered the means of OOP in Perl and got a newbie question... I've defined a class with attributes like this:

sub new { my $class = shift; my $s = {}; bless $s, $class;
  
 $s->{Laboratory}  = new MotionSensorB('Laboratory',  'senMotion_H2_S1
+');
 $s->{Fruitcellar} = new MotionSensorA('Fruitcellar', 'senMotion_H1_S1
+');

 return $s;
}

In the same package I want to loop through the attributes, that is, access the elements Laboratory and Fruitcellar:

sub event { my $c = shift;

 foreach my ??? (???) {
  print ??? . "\n";
  
}

I'm not so firm with arrays, hashes, references etc. and trying all sorts of combinations, but can't get it right. How can I achieve it?
