Temperature/Sound Level/Light Sensor

for more information.
Introduction
The PS-2140 Temperature/Sound Level/Light Sensor mea-
sures ambient temperature, probe temperature, sound level in
decibels (dB), and light level (light intensity) in lux (lumens
per square meter). Ambient temperature is automatically
recorded through the Ambient Temperature Aperture and
does not need a temperature probe. Probe temperature refers
to the measurement from a probe connected to the Tempera-
ture Probe Port on the side of the sensor. Any PASCO tem-
perature probe with a 2.5 millimeter (mm) phone plug can be
connected to the temperature probe port.
The sensor is designed to work with a PASPORT-compatible
interface (such as the UI-5100 850 Universal Interface) and
PASCO data acquisition software (such as PASCO Cap-
stone) to measure charge and voltage.
Setup the Sensor
•
Plug the sensor into one of the PASPORT input ports of
a PASCO PASPORT-compatible interface.
NOTE: If more distance is needed between the sensor and
the interface, plug the sensor into the included Sensor Exten-
sion Cable, and then plug the cable into the interface.
•
Start the PASCO data acquisition software.
Using PASCO Capstone Software
•
Click the “Hardware Setup” icon in the Tools palette to
open the “Hardware Setup” panel. Confirm that the sen-
sor icon appears with the interface’s icon.
•
Click one of the display templates in the Capstone work-
book page, or double-click an icon in the “Displays”
palette to open a data display.
•
Setup the data display to show what is to be measured
and the units for displaying the data.
Using SPARKvue Software
•
Connect the sensor to a SPARKvue-compatible inter-
face and start the software. The sensor parameter screen
opens and shows the list of measurements for the sensor.
•
In the sensor parameter screen, touch the measurement
name, and then touch ‘Show’ to open a graph display.
•
To change the measurement or the units, touch the
“Graph Tools” icon (
) and then touch the “Display
Properties” icon (
).
Record Data
•
If needed, press the ZERO button on the sensor.
•
Click “Record” or touch ‘Start’ to begin recording data.
