More Information
For more information about collecting, recording, displaying
and analyzing data, refer to the User’s Guide or Online Help
System for the data acquisition software.
Sample Data
The following graph display shows data for Temperature,
Sound Level, and Light Intensity changes inside a refrigera-
tor.
Specifications
(*The range, accuracy and
resolution of the Probe
Temperature measurement
will vary with the type of
probe connected to the
sensor.)
Sensor Usage
Tip
: Do not point the
Light Aperture at the Sun
for more than a few min-
utes.
Tip
: If connecting two or
more Temperature/Sound
Level/Light Sensors to a
multi-port PASCO inter-
face, don’t plug the sen-
sors side-by-side. Placing the sensors too close to each other
may block a sensor’s Temperature Probe Port.
Tip
: When using the Temperature/Sound Level/Light Sensor
with a PASCO datalogger for prolonged measurements
(more than 55 minutes), ensure that the PASCO datalogger
contains new or charged batteries.
Suggested Applications
•
Studying light absorption, sound acoustics, thermal
energy transfer (conduction, convection, and radiation).
•
Environmental, greenhouse, and ecological studies.
•
Comparing temperature, light, and sound from different
electrical devices.
