Using Hygroclip humidity sensor and LabView

[JeMu]

Hi,

I have a current lab set up using a NI GPIB-USB-HS controller & Labview to run and log data from a (Aquilent) frequency counter. Now I would like to add a Rotronic HygroClip for humidity & T measurements, but am unsure about the possibiliy to connect to PC and run in same/one LabView VI.

Has anyone ideas/experience on hooking up HygroClip to PC and using LabView alongside with other instruments?

Any hint or ideas appreciated,

thanks

Hi Jemu,

You would need to create your own drivers to interface Rotronic software to LabVIEW.  For many common instruments, you can find the drivers on the NI Instrument Driver Network:

I've tried looking there for Rotronic drivers on the instrument network but didn't find any.  If you can create/find the LabVIEW drivers for your Rotronic instrument, there should be no problem controlling both the frequency counter and the Rotronic instrument in the same VI.

Hy JeMu,

Did you find the way to communicate with the rotronic?
if so could you please contact me
Many thanks

Hi Fidel

No, I have actually not followed up and implemented the Rotronic and Labview setup. It should be feasible but I remember it not looking a straight forward thing to do. 

Good luck,

Hello, You can connect to the Rotronic HygroClip through their loggers, e.g. the HygroPalm or HygroLab, using the RS232 port (through a usb converter if you wish). It is fairly easy to set up using the 'connect to serial' example vi s available in LabView, and then extract the data from the string. Info on the data stream is given in the back of the HygroLab manual (available as a pdf on line). I have not explored extracting data directly from the probe yet... but it would require writing dedicated drivers i suspect.

Hello I have an Hygropalm 3 with docking station and I want to use Labivew to read the sensor output? Does anyone have found the driver labview code for this device?

Dear Blue:

Do you have the vi for the hydrolab? I am trying to buy either the hydrolab or hydroplam but I want to use Labivew to record temperature and humidity.

Hi David,

I'll see if i can dig it out tomorrow. It was only a lash up, but it worked.

Hi David,
 
Please find the VI for reading the HygroLab attached. It should be easy to change the string to get it to work with a HygroPalm, though i haven't tried it as i don't have one!

Thank you very much. You save me big time.
