    So you have a datasheet?

    I'm betting the text is the trick, that or there is a notch somewhere you can't see in the picture.

    yes, i have a datasheet.
    but the datasheet does't show where is the front of the sensor.
    so i can't get where is the left side and where is the right side.

    Look at the text, one side is up, the other side is down. This defines a left and a right.
