Logging of Remote Temperature and Humidity data

[billsspace]

I am starting a project to gather data for humidity and temperature in
several labs in our building. The sensors will be networked and one
central computer needs to grab the data from them. I'll need to log and
store data 24/7 and create alarms and send pages when readings go out
of spec. I was looking for some general help and ideas form anyone.
Canned VI's, or any information would be very appreciated.

What version of LabView are you using?  What sort of sensors do you have in mind?  How do you plan on networking them?  I am sure there are as many possible solutions as there are members of this forum.  Which one will serve you best is dependent on what software and hardware you have availible.

If you could concider a ready built solution, I can point you at one of my customers who offers everything you mentioned and is already 21-CFR-11 compliant.

If interested e-mail me at

Otherwise please forgive this distraction,

Bill,

I just wanted to back up Jason suggestion. There are many ways to do what you want within LabVIEW, and much of it is dependent on what hardware you have and version of LabVIEW. There are quite a few shipping examples that come with the DAQ driver (if you are using a DAQ board) that show you how to set up a continous acquistion, and there are also examples to show you how to log data. So if you could post the hardware you are using, or if you are in the stage to get hardware let us what you would need it to do, and we can offer more suggestions. Take care,

Hello,

   My application is also Data logging 24X7, I am using Lakeshore 218 temperature monitor and taking data to PC by RS232 interface. I don't have problem to plot data on chart. But in my application i may have to look some time historical data.It is little bit SCADA type application but only data display. I tried to find some example but i couldn't understand , how to implement that. How it is possible to write/read same file at a time. My data logging is continous 24X7 and for example i want to see trend of temperature 1Hour back for 30 minute. How it is possible. because when i look at historical data same time datalogging is running.

Is there any example available for such application? or can you guide me how i can do this?
