Anemometer
(Order Code ANM-BTA)
The Anemometer is a device for measuring wind speed.
How the Anemometer Works
The Vernier Anemometer is an impeller-type anemometer with the axis of rotation
parallel to the direction of the wind. It uses a magnet located in the impeller and an
inductor. The wind causes rotation of the impeller, the magnet, and the shaft. The
rotation of the magnet produces an electrical signal proportional to the wind speed.
Using the Anemometer
To use the Anemometer, hold it so that the wind blows directly into the
Anemometer. This will cause the impeller to spin. You can also attach the accessory
rod to the standard camera mount found on the back of the Anemometer and mount
it on a ring stand.
Potential Uses for this Sensor
The following is a partial list of activities and experiment that can be performed
using this sensor.
Measure the wind speed of air generated by a variable speed fan.
Use an Anemometer, a Current Sensor, and a Differential Voltage Probe to
investigate the effect of design, number, and size of rotors and blades of a
windmill's electrical energy output.
Use an Anemometer and an Infrared Thermometer to determine how wind speed
affects the rate of cooling of an object.
Investigate why wind speed is slower over land than it is over the ocean.
Use an Anemometer and a compass to determine wind direction.
Collecting Data with the Anemometer
This sensor can be used with the following interfaces to collect data:

Here is the general procedure to follow when using the Anemometer:
1. Connect the Anemometer to the interface.
2. Start the data-collection software.
3. The software will identify the Anemometer and load a default data-collection
setup. You are now ready to collect data.
Data-Collection Software
This sensor can be used with an interface and the following data-collection software.
Logger
Pro
This computer program is used with LabQuest 2, LabQuest,
LabQuest Mini, LabPro, or Go!Link.. The Anemometer requires Logger
Pro
3.8.3
or newer.
Logger Lite
This computer program is used with LabQuest 2, LabQuest,
LabQuest Mini, LabPro, or Go!Link.
LabQuest App
This program is used when LabQuest 2 or LabQuest is used as a
standalone device. The Anemometer requires LabQuest App 1.5 or newer.
DataQuest™ Software for TI-Nspire™
This calculator application for the TI-
Nspire can be used with the EasyLink or TI-Nspire Lab Cradle.
EasyData App
This calculator application for the TI-83 Plus and TI-84 Plus can
be used with CBL 2, LabPro, and Vernier EasyLink. We recommend version 2.0
or newer, which can be downloaded from the Vernier web si
te,
www.vernier.com/easy/easydata.html, and then transferred to the calculator. See
the Vernier web site, www.vernier.com/calc/software/index.html for more
information on the App and Program Transfer Guidebook.
DataMate program
Use DataMate with LabPro or CBL 2 and TI-73, TI-83,
TI-84, TI-86, TI-89, and Voyage 200 calculators. See the LabPro and CBL 2
Guidebooks for instructions on transferring DataMate to the calculator.
LabVIEW
National Instruments LabVIEW™ software is a graphical
programming language sold by National Instruments. It is used with SensorDAQ
and can be used with a number of other Vernier interfaces. See
www.vernier.com/labview for more information.

Calibration Information
You should not have to perform a new calibration when using the Anemometer. We
have set the sensor to match our stored calibration before shipping it. You can
simply use the appropriate calibration value that is stored in the data-collection
program.
