Introduction
The Weather Sensor measures
• barometric pressure (in inches of Hg, hPa, or mbar),
• absolute humidity (g/m
• 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.
