Getting sensor values ​​per second

Is there any way I can read a sensor per second? What is SENSOR_DELAY_NORMAL speed in seconds?

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

The delay set by SENSOR_DELAY_ * is only the suggested delay , actual results can be faster or slower. If you only need one read per second, you can use the slowest speed (SENSOR_DELAY_NORMAL), it should be updated approximately 5 times per second. You will need your own deadlines if you want to do something exactly once a second.
