In order for the program to function, it will need to collect data from the SkyAlert weather module. Two different methods of data collection are provided for this purpose, “Local” connection or “Remote” connection. Using the “Local” connection means the weather module is connected directly to a USB port on the computer running the program. For “Remote” connections, the weather module is connected to a networked computer running the SkyAlert Remote program and the data is retrieved over a network connection. This method can be useful for connecting multiple computers to a single weather system module or as a failsafe backup in case a module malfunctions. Either way, the computer connected to the weather module will need to have the hardware drivers installed and will need to be running either the SkyAlert program or the SkyAlert Remote program.
Connect the weather module to a free USB port on the computer, select the “Local” radio button, select the appropriate com port from the drop down Com Port selection menu and click the “Connect” button. If you are uncertain which port the weather module is connected to, continue selecting com ports until the label adjacent to the Connect button indicates that the device is connected. Note: As long as there are no hardware changes, this only needs to be done the first time the program is run. On subsequent sessions, the program will automatically connect to the module when it is launched.
Before continuing, connect the SkyAlert module to the remote computer and launch the SkyAlert Remote program. Launch SkyAlert on the local computer, open the Settings page and click “Remote” radio button. A navigation button adjacent to it will appear. Click on the button and navigate to the location of the data file generated by the SkyAlert Remote program. (The default name for this file is “remotedata.txt”). Note: As long as there are no file location/name changes, this only needs to be done once. On subsequent sessions, the program will automatically connect to the remote file.
Enable Backup SkyAlert:
Check this box if an auxiliary remote weather module is connected to another computer on the network.
Use this drop down to select the com port that the SkyAlert weather module is connected to then click the ‘Connect’ button to establish the connection.
Top Most Window:
Ticking the “Top Most Window” checkbox will keep the main menu as the top-
Weather Data File Settings:
When the “Create Weather File” checkbox is ticked, the program will generate and save a standard one line weather data file (i.e. Boltwood II) to a specified file location. Click on the adjacent “Save to” button to select a name and file path to save the file to.
The “Cloudy Offset” setting can be adjusted to determine when the sky is cloudy.
This number is the difference of the measured sky temperature subtracted from the
measured ambient temperature and will determine when the weather data file reports
a cloudy condition. You may need to adjust this setting to suit your particular climate
or conditions. The default value is -
The “Wind Limit” setting determines the maximum allowable wind speed before an unsafe wind speed alert is reported in the weather data file.
The “Humidity” setting can be set to the desired maximum humidity level before an alert is set.
The “Temperature” setting threshold can be adjusted to set an alert if the ambient temperature drops below the set value.
Checking the “Dew Point” check box will set an alert if the dew point is reached.
Checking the “Daylight” check box will set an alert if daylight is detected.
Checking the “Error/Malfunction” check box will set an alert if any data or hardware malfunction should occur. (It is recommended that this check box remains checked unless you have a specific reason to leave it unchecked)
Set the name of the graphs page by typing a name in the “Graph Page Title” text field. This is the title that will appear at the top of the Graph window.
The “Graph Timeline” setting determines the length of the timeline the graph will show. This can be set from one to three days. After the timeline setting has been reached, the oldest graph data will be overwritten.
Ticking the “Top Most Window” checkbox will keep the graph page top-
Tick the “Save Graph Image to File” checkbox if you would like a snapshot of the graph saved as an image file. This is necessary if you plan on uploading an image of the graph to the web. Click on the adjacent “Save to” button to set a name and file path to save the image to. Image files can be saved as .png or .jpg. A new image will be generated each time the weather data is updated. If the ftp client is connected, the current graph image will be uploaded to the host.
The settings instructions are sorted by groups starting at the top left of the settings page.
After finishing the installation, connect the SkyAlert module USB cable to a free USB port on the computer.
Note: Some USB 3.0 chipsets may not function correctly with SkyAlert. If you experience difficulties, connect SkyAlert to a USB 2.0 port. (USB 3.0 ports can be usually be identified by a blue connector.)
Proceed by selecting the "Tools" selection from the drop down menu and clicking on the "Settings" option. This will bring up the "Settings" page.
When the program is started, the main dialog will appear displaying time, date, current weather conditions and a few options.
The values for the moisture sensor can be adjusted to fine tune the thresholds for dry, damp and rain if needed. The measured value currently generated by the weather module is displayed below the adjustment setting to facilitate the adjustment. The default values are Dry=990 and Rain=970.
The zero wind speed setting can be adjusted to fine tune the wind speed setting. Adjust the setting so that the wind speed is slightly above zero (i.e. .001) when the wind sensor is completely shielded from any breeze or turbulence. The default value is .200. Note: although the value seems small, the zero wind volts setting has a major impact on the indicated wind speed.
Normally, the calibration of the IR sensor can be left at the default setting of zero. Adjustments can be made if necessary.
The light sensor can be calibrated to match your particular environment and installation position. The default values are Day=500 and Dark=250.
The Ambient temperature sensor can be calibrated if needed. The default setting is zero.
Default is zero.
Barometric Sensor: (Where available)
Adjust the pressure value to match a current known value in your area (local airport web site, etc.)
Cloudy/Very Cloudy Offset:
This adjustment dictates the difference between a Cloudy condition and a Very Cloudy condition. You may have to experiment with this setting to get optimum results.
The solar offset makes an adjustment to the ambient temperature based on whether or not direct sunlight is shining on the weather module.
The Offset value should be adjusted to the amount of temperature increase that is noted when the sun is shining on the weather module.
You can set the relative time of day for the algorithm to begin by setting the ‘Start’ value to how many minutes after sunrise that the sun will begin
to strike the module. Conversely, set the ‘Stop’ value to the approximate time that the sun will cease warm up the weather module.
SkyAlert has several feature and options which are available from selecting menus from the drop down menu bar of the Main dialog.
From the “File” menu drop down, a daily weather file is available. This file shows weather conditions recorded every ten minutes for the last 24 hours. Also available from the file drop down is a shortcut to the folder location of archived weather logs. Weather logs are kept up to one year before they are deleted.
The “Tools” menu drop down contains several selections which are outlined in the pages below.
Weather graph images can be optionally uploaded to a web host for web page display. To connect to a web host, enter hosting credentials in the Hostname, Username and Password fields and then click the “Connect/Disconnect” button. If a connection is successfully established, in a few moments the list box to the right will populate with the names of the files currently on the server.
When the ftp browser list is populated, the contents of the server will appear with
folders at the top followed by files listed in alphabetic order. To open any of the
folders, double click on the <Folder> title. With the cursor positioned within the
file list, right click for more navigation options. After a location has been determined
to upload the file to, type in a name for the file in the “Filename” field. (The
default filename is weathergraph). This will be the filename used in your html code
to display the image on a web site. It is not necessary to add a filename extension
as this will be automatically determined by the file image type. The upload interval
can be set by adjusting the Upload Interval control to the desired interval time.
Click on the “Save” button to save the settings and click the “Close” button to continue.
In addition to uploading the image file, SkyAlert will upload a copy of the one line weather data file in the same folder. This can be be useful for sharing weather data to multiple locations that cannot otherwise access the file.
Note: The ftp browser does not support double-
