Hi darckreign1984,

 

Since your sensor uses bidirectional serial communication I believe you will be using mostly the NI-VISA and NI 488.2 drivers.  We do have a section on the National Instruments website that focuses on drivers written for third party instruments found at ni.com/idnet.  I did a quick search for the company that makes the SHT11(Sensirion) and found two plug and play drivers that have been written for the SHT71 and SHT75.  I believe these are going to be your best bet as a starting off point and might be something you may need to tweak to get it to work with the SHT11.  Please find the link below to the drivers.

Happy programming!

The NI-DAQ version may not support your version of LabVIEW.

Here is the compatability matrix.  MAX Software tab will tell you what versions of LabVIEW and NI-DAQ you have installed

Look at this example: http://forums.ni.com/t5/LabVIEW/Sensirion-SHT15/m-p/1589710?requireLogin=False

 

You have to use the DIO to communicate with that sensor.  I know there are examples in the discussion forum that show how to do this.

 

Good Luck

Hi Kyle,

 

I am a novice who would like to use Sensirion's SHT75's sensors with LabView (ver. 11.0 32-bit, running on Windows XP) for simultaneous logging.

 

Funds are too limited to purchase the "Evaluation Kit EK-H4 for Humidity Sensors SHTxx"

 http://www.sensirion.com/en/01_humidity_sensors/07_evaluation_kit/02_relative_humidity_ek-h4.htm which appears to operate with a proprietary serial language and - so I am seeking advice on alternatives to interface and operate these sensors. 

 

I see from your post where the drivers can be found. Do you have any advice on the remaining (hardware, and any software) items required? e.g. to interface the SHT75 with the PC. 

 

Thank you!

I should add that my department might already have NI Multifunction DAQ's I could use, avoiding this cost. I see the drivers for "NI-DAQmx 7.5 - Windows 2000/XP/NT" can be found here http://joule.ni.com/nidu/cds/view/p/id/331/lang/en.
