Vortex Wind Sensor and Data Logging Software
Full Product DescriptionSpecificationsAdditional PhotosOwner's ManualsWarranty Support
The Windware Kit includes everything necessary to collect wind speed data: a quality Inspeed Vortex Wind Sensor, wire, and an interface cable to the PC.
25 feet of wire come standard, custom lengths available on request. Tested fine with more than 500 feet of wire.


The live display provides a real-time readout of the following information:
  • Current wind speed (in the gray bar)
    Maximum wind speed since last reset, as well as the time stamp when the max was recorded.
    Average wind speed since the last Reset.  The date and time of the last reset is also shown. 
    Minimum wind speed since last reset, as well as the time stamp when the min was recorded. 

If the Alarm Speed is exceeded, the color of the Current speed will change and the Digital Output will be triggered.

The live display also includes the following controls:

  • Reset Displays:  to reset the Live Displays (not the data acquisition)
    Reset Alarm: to reset the alarm and digital output
    Data Log On/Off: to start and stop data logging
    Starts logging automatically on boot/reboot so if you leave your computer unattended and there is a power outage, on reboot it will continue logging automatically.
    Setup:  to select units, logging, etc.

Wind Speed Data

Setup provides the following capabilities:

  • Units selection:  mph, kph, knots, m/sec, and  Beaufort
    COM Port:  the port into which the Vortex wind sensor is connected
    Alarm Speed:  the wind speed at which the Live Display numbers will change color and the digital output will switch.
    NEW (December 2009): you can now click "Reset at:" to automatically reset the alarm at the % drop of your choice.
    Filename:  the name and location of the data file
    Interval:  the number of minutes between stored data sets.  It is also the interval over which the stored wind speed will be averaged. 
    (Note: this is not the same average as  the Live Display, which averages over the entire time since the live displays were last reset).

 The data stored includes the current speed, the max and min during the previous storage interval, and the average over the interval selected. 

 It is stored in ASCII format such that it can be read by virtually any graphing software.  An example is shown here where the storage interval was one minute.

Stopping and starting the program APPENDS the new data and does NOT overwrite existing data.

Windware Data Files

SPEED RANGE Approx. 3 to approx. 150 mph. (~5 to ~ 240 kph)
ACCURACY better than +4% of reading (ex: 20 mph +0.8 mph)
SAMPLING RATE peak wind gusts are monitored at a constant rate of 1 Hz (once per second)
SAMPLING INTERVAL minimum 1 minute, user-selectable at one minute intervals
DATA STORAGE INTERVAL same as the averaging interval: minimum 1 minute, user-selectable at one minute intervals
DATA FILE Data files are created in ASCII format with time and date stamp
Data stored includes current, and max/min/averae for the selected interval
The amount of data stored depends on available disk space 
Stopping and restarting the data collection APPENDS data in the same file, does NOT overwrite
OTHER APPLICATIONS Windware 1.0  Wind Speed Data Logger is a high speed background program, utilizing less than 1% of CPU power on a typical, modern PC.  Therefore, other programs should run simultaneously without problems.

at least one COM port needs to be available for the wind sensor input.
 A 9-pin COM port connector and cable is available from Inspeed (see below).
 For do-it-yourselfers, attach to the COM1 9-pin connector as follows:  WIND SENSOR:  pins 4 and 6, no polarity.  The Alarm output is on pin 7(RTS) with respect to pin 5(GND). It will go high(RS232 positive level) when it trips, and return low(RS232 negative level) when reset. The RS-232 output is specified to be in the range of 5 to
 9 volts (positive or negative) when driven into a maximum load of 300 ohms.

Attach to the COM2 25-pin connector as follows: WIND SENSOR is connected between pins 20(DTR) and 6(DSR). The alarm output is on pin 4 (RTS) with respect to pin 7 (Signal ground). It will go high (RS232 positive level) when it trips, and return low (RS232 negative level) when reset. The RS-232 output is specified to be in the range of 5 to 9 volts (positive or negative) when driven into a maximum load of 300 ohms.

USB: Windware will work with a COM to USB adapter (OPTION)

GRAPHING Sorry – no graphs included at this time – just data - but making them is a piece of cake.
      (it takes only seconds to create a graph using Microsoft Excel®...).
OPERATING SYSTEM The wind speed data logging software is compatible with PC’s running Windows® XP, 2000, Vista, Windows 95, Windows ME, and Windows 98.

Windware 1.0 Wind Speed Data Logging software is only compatible with the Inspeed Vortex wind sensor, which provides one digital pulse per rotation. One wind sensor is included in the Windware Kit.
Current Vortex Users:   Any Inspeed Vortex Anemometer Wind Sensor can be used with the data logging software.  Simply disconnect the cyclometer display and connect the wind sensor to the PC.  Do NOT try to use both the cyclometer and Windware at the same time - it could damage the cyclometer).
 The interface from the wind speed sensor to the PC is via the serial COM port D-connector.  A 9-pin D-sub connector is included in the complete kit.  For existing Vortex users, a connector is available from Inspeed, or simply connect the two wires from the wind sensor to pins 4 and 6 of a standard 9-pin serial port connector (no polarity), or to pins 20 and 6 on a 25-pin COM2 connector.  (See COM Ports above).
A surge protector is also available - and strongly recommended!  (To protect your computer from the likes of lightning...)

Comes standard with 25 feet of wire. Custom lengths available on request.
Tested fine with over 1,500 feet (500m) of wire.
Works with any 2-conductor wire.

DIGITAL OUTPUT ALARM The Wind Alarm is configured to change the color of the Live Display and to switch a digital line on the COM Port:  the alarm is on pins 7 and 5 of the 9-pin COM1 connector, or on pins 4 and 7 on a 25-pin COM2 connector (see COM Ports above). 
MULTIPLE SENSORS Windware requires one COM port for each sensor.
It is possible to run multiple copies of Windware with multiple sensors provided each has its own COM port.
Note that settings will only be auto-saved for one copy; closing and re-opening multiple Windware requires that you check to see that the proper settings are in place.
Anemoemter used in Kenya

Thank you for Inspeed's donation of an anemometer to aid in our efforts to provide power for a medical clinic in the village of Lare Njoro, Kenya. The installation went well.  We installed the anemometer on quest house near the clinic.  With several months of data collection we should know if wind power is a feasible option for the clinic.

The clinic is part of a Mercey Center Foundation development plan and will be used by the Virginia College of Ostiopathic Medicine (VCOM). Many students from VCOM will have the opertunity to rotate through the clinic to gain medical experience as well as serve the people of Lare Njoro. Thank you again, and I hope you enjoy the attached pictures.

NOTE TO CURRENT USERS: Please make sure you are using the correct version of Windware:

M1 Rotor
If the rotor on your Vortex looks like this you should be using VERSION 1.1X ("M1 Rotor")

D2 Rotor
If the rotor on your Vortex looks like this you should be using VERSION 1.2X ("D2 Rotor")

Different rotor styles have different calibration numbers - using the incorrect version will produce incorrect data!

If you open the box and it is not what you wanted or expected, return it within 2 weeks in as-new condition for a 100% refund (not including shipping). We provide a 1 year 100% warranty on any defective parts and/or any failure resulting from normal use.
