====== Ball Speed Sensor Placement ======

**Ball Speed Sensor Placement Requirement:**
^Parameter	^	Placement Requirement	^
|Position  |Place the ball speed sensor directly in front of or behind the ball's flight path. In front: measures the ball's hit speed; behind: measures the ball's landing speed.|
|Angle  |Keep the ball speed sensor at a 0-degree angle to the ball's flight direction. Any angular deviation (cosine angle) will cause the measured speed to read low.|
|Height  |The height should be kept roughly level with the ball's flight height.|
|Distance  |The distance from the hitting point should be less than 152 meters.|

**Baseball Court Placement**\\
For best results, place the ball speed sensor about 9 meters behind home plate.\\
Note: Line drives hit toward the home run area are measured relatively accurately; however, balls hit toward first base, third base, or fly balls will show lower speeds due to angle errors.\\

**Tennis Court Placement**\\
It is recommended to place the ball speed sensor at both ends of the court and near the center.\\
