The student can use just one sensor to study objects such as a pendulum, or
two can be used for a variety of other experiments.
Output Range: +/-5V
Default scaling Value: N/A
Laser Wavelength: 650nm
Laser color: Red
1. Install the IX-ELVIS board into the National Instrument ELVIS platform or the
IX-myDAQ board onto the NI myDAQ. If using ELVIS, connect the ELVIS power supply
to the ELVIS unit and connect it to the computer via a USB cable. Ensure both of
the power switches are in the â€œonâ€ position. For the myDAQ, connect it to
the computer using the USB cable.
2. Connect the MINI DIN7 connector of the LSN-100 to either CH1 or CH2 of either
the IX-ELVIS or IX-myDAQ board.
3. Open the recording software, select the channel that the LSN-100 is connected
to and ensure the range is set to +/-5V.
4. Set up the sensor and the tape so that the laser is focused on the tape and
the object is in between the tape and the sensor.
5. For a pendulum, set the beam in the path at the lowest point of the swing.
6. The voltage goes up when the laser is shined on the light sensor and down
when the path is blocked.
*Note: The signal may be inverted when using the myDAQ setup.
