Ball drop with motion sensor
Special features:
  • Large 38 mm instrument grade sensor element
  • Red Led to indicate stable readings
  • Case designed to protect the sensor element
  • Case size places the sensor at optimal height for time distance exercises
  • Fast 50 Hz recording period
  • 8 predefined ranges
  • The Motion sensor is a sonar device that emits ultrasonic pulses, which reflect off an object. Maximum sample rate is 50 per second (50 Hz) (20 ms interval between samples). Automatic correction for air temperature incorporated into the Distance ranges. The Time range measures the time taken for the pulse to travel to an object and back so can be used to measure the speed of sound.
