SQM reader
Publisher:Jurij Stare
The following prerequisites are required:
  • Microsoft .NET Framework 4.6.1 (x86 and x64)
If these components are already installed, you can launch the application now. Otherwise, click the button below to install the prerequisites and run the application.
SQM type Select SQM-LE or SQM-LU
SQM-LE IP Address Address of the SQM-LE you are trying to read.
SQM-LE Port SQM-LE port.
SQM-LU COM Port The list shows available COM ports. Select the COM port your SQM-LU is attached to.
Read only when sun below Needs to be an integer (degrees). -18 astronomical darkness, -12 nautical, -6 civil. It's best to have it at -18 or a little above this value so the chart is easier to read.
Latitude/logitude Latitude and logitude of the SQM. This is only used if you have the above criteria set, so the application can calculate the sun altitude key The key you were given.
Enclosure offset If your enclosure has a glass window then this value is substracted from the reader value. The window reflects some of the light from the sky, so the reader reports the sky a bit darker. This offset solves this issue (the original enclosure reports sky to be dimmer by 0.11 magnitude, so this is the default value)
Reader interval Interval in seconds for each reading. Needs to be above 60 seconds. Usually 120 or 300 seconds is a good value
Begin reading at start If checked the application starts reading as soon as it is opened. Useful if the application is started when Windows starts.
Start/Stop Starts or stops the continues reading.
Log Show the current reading or any errors. If nothing is shown after reading is started then the app is having problems contacting the SQM device.
