title: How to poll sensors slowly?
body: <p>I'm writing an app which copies sensor data to a text file over a long period of time. So I would like to use as little battery as possible, hence the requirement of a slower polling time.</p>
  
  <p>Currently I have this as my listener:</p>
  
  <pre><code>sMgr.registerListener(this,sProximity,5000000);
  </code></pre>
  
  <p>which I believe should poll the sensor every 5,000,000 microseconds. However, it seems to be polling it at ~4 times a second. This actually doesn't change no matter what value I put in.</p>
  
  <p>At the moment I'm just displaying the sensor data in the app with the onSensorChanged method override - could this be why it is polling the sensor so frequently?</p>
