Getting sensor values per second

Is there any way that I can get the sensor reading per second?
what is SENSOR_DELAY_NORMAL rate in seconds?

sm=(SensorManager)getSystemService(SENSOR_SERVICE);
accelerometer=sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
sm.registerListener(this, accelerometer, SensorManager.SENSOR_DELAY_NORMAL);

Answer

The delay specified by SENSOR_DELAY_* is only a suggested delay, actual results might come faster or slower. If you only need one reading per second you can use the slowest rate (SENSOR_DELAY_NORMAL), it should update about 5 times per second. You'll need your own timing if you want to do something exactly once per second, though.
