Full Example

var accelerometer = require('accelerometer');
var recorder = require('recorder');

var dataResult = accelerometer.data();

var accelerationDetectedFilters = {
    "period": exampleValue,
    "vector": exampleValue
};

recorder.save({
    'accuracy' : accelerometer.accuracy(),
    'deltaX' : accelerometer.deltaX(),
    'deltaY' : accelerometer.deltaY(),
    'deltaZ' : accelerometer.deltaZ(),
    'minDelay' : accelerometer.minDelay(),
    'model' : accelerometer.model(),
    'timestamp' : accelerometer.timestamp(),
    'vendor' : accelerometer.vendor(),
    'version' : accelerometer.version(),
    'x' : accelerometer.x(),
    'y' : accelerometer.y(),
    'z' : accelerometer.z(),
    'json' : accelerometer.data()
});

accelerometer.onAccelerationDetected(accelerationDetectedFilters, function(data) {
    recorder.save(data);
    recorder.sync();
});
