  1. Motion Sensor Muhajir Ab. Rahim School of Mechatronic Engineering, KUKUM

  2. Introduction • Designed to measure the rate of change of position, location, or displacement of an object that is occurring. • The primary form of motion sensor is the accelerometer that can provide acceleration, speed (or velocity), and position information.

  3. Type of Motion • Rectilinear • Angular • Vibration • Shock

  4. Accelerometer Principles • In applications that involve flight, such as aircraft and satellites, accelerometers are based on properties of rotating masses. • In the industrial world, however, the most common design is based on a combination of Newton's law of mass acceleration and Hooke's law of spring action.

  5. Accelerometer Principles • Newton’s Law • Hooke’s Law

  6. Types of Accelerometer • Potentiometric • LVDT • Variable Reluctance • Piezoelectric

  7. Piezoelectric • Based on property exhibited by certain crystals where a voltage is generated across the crystal when stressed • When exposed to acceleration, the test mass stresses the crystal by a force (F=ma), resulting in a voltage generated across the crystal
