Labview Drivers for Wireless Sensor Networks

Hey Milky,

The circled blocks in grey are just delays in the code. They're not always necessary depending on the hardware.  The yellow blocks are index arrays that grab particular NodeIDs for you to specify which ID feeds into the Read Vis.  The simplified version of the VIs should work fine for you and I recommend using it since it's successfully getting your data.

Thanks David for explaining 🙂

I've attached my vi file. This is how I intend to design my GUI but I haven't figure out how should I connect the graphs waveform to my sensors on MTS400 and how should I connect my nodes to write to a spreadsheet in my block diagram... Can you please help to show me how?

Hey Milky,

What data from the clusters are you wanting to write to the spredsheet?  All of it? Just Light, just temperature, just humidity?

[MiLKy83]

Hi David, if possible, I'd like to wirte all the data from the clusters to the spreadsheet. But if it is simpler to just write temperature, humidity and light, I may consider doing so. Please advice. Thanks

Hi Milky,

You can use Cluster to Array function in the Array Function palatte to write the element values in cluster into spreadsheet.

Note: This is true, only if the cluster has elements(variables) which has same dataype .

Hey David,

I'm so excited tat I did it! I could monitor my waveform chart already as attached. 🙂

I'm still trying to figure out how to make the time on my waveform chart to follow the time stamp on my node. Can you teach me?

I still haven't figure out how to write the data frm my nodes to a spreadsheet... Pls show me how can I do it...

Hey Kim,

If you're only wanting to write the four graphs you're taking then writing to the spreadsheet is simple. See attached photo.

Thanks,

David, your drawing is so much simpler than mine. Can you please send me your vi file? There are some features that I don't understand without the context help in JPG file.

Thanks!

Hi David,

I tried to connect the write to spreadsheet function but I get the error as attached. How can I fix it?

hi Kim,

You need to give a valid path to the  Write to spreadsheet.vi  to store the data.

Rgds,
