ABSTRACT:
Disclosed is a motion sensor for sensing movement of an object to be monitered, the motion sensor comprising a support disk having a concave upper surface, a ball rotatably put on the support disk, and a piezoelectric element attached on the support disk. If the object attached with the motion sensor inclines or swings, the ball rolls on the support disk to cause the support disk to vibrate. The vibration is taken out as an electric signal by the piezoelectric element and the electric signal informs of the fluctuation occured on the object. An electromagnet, upon energization, prevents rolling movement of the ball.
