title: Getting sensor values per second
body: <p>Is there any way that I can get the sensor reading per second? 
  what is SENSOR_DELAY_NORMAL rate in seconds?</p>
  
  <pre><code>sm=(SensorManager)getSystemService(SENSOR_SERVICE);
  accelerometer=sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
  sm.registerListener(this, accelerometer, SensorManager.SENSOR_DELAY_NORMAL);
  </code></pre>
