Humidity/Temperature/Dew Point Sensor

PS-2124A

Quick Start

1. Connect the Humidity/Temperature/Dew Point Sensor to

your PASPORT interface.

2. If you are using a computer, connect the interface to it and

start DataStudio.

3. Press or click the start button to begin recording data.

Introduction

The Humidity/Temperature/Dew Point Sensor measures absolute

humidity (in units of g/m

) and air temperature (in °C, °F, or K).

From these measurements, it calculates relative humidity and

dew point.

All of these measurements are recorded by your PASPORT inter-

face or DataStudio software. By default, data is recorded at the

rate of 2 samples/s. The maximum rate is 10 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 humidity, temperature, and dew point as they

change over time.

• Compare humidity and temperature at various locations.

• Monitor weather conditions.

• Monitor greenhouse conditions.
