Sensirion SHT15

[nooobieee]

Hi ,

      Has neone used the sensirion Rh and temp sensor with USB 6211 ? I found a discussion where the NI USB 6009 was used , and I tried the routine with USB 6009 it works. However When i try using it with USB 6211 it does not. The major difference is the D I/O lines on 6211 are not bi directional.

Here is the code I tried which worked with usb 6009 which was uploaded earlier by another labview user.

I'm using the SHT15 sensor chip.

nooobieee,

It'd be nice to know what type of errors you're running into or why the code isn't working.  Could you provide that info or a screen shot the errors? Also, you can always try using a standard shipping example from LabVIEW.  You can find examples by going to Help » Find Examples. Then, double-click Hardware Input and Output » DAQmx » Analog Measurements » Temperature.

Please post the missing VI: SensirionReadWod.vi

Hi!
I'm an engineering master thesis student @ Politecnico di Mlano.

I'm trying to use Sensirion SHT15 with a PIC32, but without any results.

So I would like to make some test with your VI, just to check if it's a problem of my board or if it's a problem of the sensor.

In the first post you uploaded:

- Sensirion Demo.vi

- Sensirion_SubVI.vi
- Sensirion SendWord.vi

The problem is that the subVI Sensirion_ReadWord.vi is required but is missing, so I'm not able to run the software.
Could you please upload also this file?

Pleease, it's very very important.

Thank you in advance!

Hi Silvia,

I would recommend creating a new topic, because it will get more visibility than posting on a thread that has be inactive for 2+ years. I sounds like you are trying to communicate over i2c, which typically requires hardware to enforce timing. You can try the NI USB-8451 which is designed to run multiple communication buses. This White Paper outlines how to use i2c with the USB-8451: http://www.ni.com/white-paper/5767/en/
