The PASCO CI-6742 Motion Sensor II is a sonar
ranging device with a sensing range of 0.15 to about 8
meters. When used with an interface, the Motion
Sensor II emits ultrasonic pulses and detects pulses
returned as echoes from the target. The
ScienceWorkshop program calculates the distance to
the object from the speed of sound and half the sonic
pulse round trip time. The program can also calculate
velocity and acceleration from the distance and time
measurements. The trigger rate for the Motion Sensor
can be set in the ScienceWorkshop program to
trigger as few as 5 times per second (for recording
relatively slow events over large distances) or for as
many as 120 times per second (for quick events such
as a free-fall experiment).

The CI-6742 Motion Sensor II has several

improved features, compared to the CI-6529

Motion Sensor:

• reduced minimum distance of operation

• reduced sensitivity to false targets

• front panel LED that lights when the Motion

Sensor acquires the target

• additional mounting and positioning options

• compatibility with Texas Instruments

®

 and

Casio

®

 scientific calculator-sensor interfaces

• compatibility with ULI interfaces

Important Operating Note: When operating in

the Std. mode, it may be necessary to tilt the

transducer up 5-10 degrees for best

performance, as shown.
