Hello All,

 

I have been looking at the output string from my AAG Cloudsensor and I can understand the majority of the data format but I am struggling with the long number it seems to generate.

Currently my unit is returning a value of 044014.73131 

Can anyone shed any light onto how it arrives at this figure and what it refers to.

 

Kind regards

Martin

I believe the AAG Cloudsensor file follows the standard Boltwood output. Therefore this link will define values from left to right.

I'm guessing that the number you are referring to is the elapsed days since last write.

 

I hope this helps.

Cal

Hello All,

 

Thanks to Cal and the link provided, We were struggling to understand what the 044014.73131 was and its defined as the number of days since 1/1/1900 and the second part is 10000 divided by 24 hours (which resets at midnight).

We now understand the complete data string that makes up the file.

 

Regards,

 

Martin
