Quick Start
1.
Connect the Weather Sensor to your PASPORT-compatible
interface.
2.
If you are using a computer, connect the interface to it and
start the PASCO data acquisition software.
3.
Touch or click “Record” or “Start” to begin recording data.
Introduction
The Weather Sensor measures
•
barometric pressure (in inches of Hg, hPa, or mbar),
•
absolute humidity (g/m
3
),
•
and air temperature (°C, °F, or K).
From these measurements, the sensor calculates
•
relative altitude,
•
relative humidity, and
•
dew point.
All of these measurements are recorded by your PASPORT inter-
face and the PASCO software. By default, data is recorded at the
rate of 1 sample/s. The maximum rate is 5 samples/s.
For Best Results
•
Keep the sensor out of direct sunlight when making mea-
surements.
•
If you intend to leave the sensor outdoors, place it at least
1 m above the ground and be sure that it will remain shaded
and dry.
•
If the sensor will be in a still environment, such as a terrar-
ium, use a small fan to maintain air flow through the sensor.
Important: Do not immerse the sensor in liquid or allow it to get wet.
Suggested Uses
•
Compare pressure, humidity, temperature, and dew point as
they change over time.
•
Compare pressure, humidity and temperature at various
locations.
•
Monitor weather conditions.
•
Monitor greenhouse conditions.
