Plurality of Sensor - WSN

Hi everybody.
I am new to wireless sensor network concepts. When I was studying about sensor tags, I frequently came across "Plurality of Sensor". What is the exact meaning of this term (or) what is the role of "Plurality of Sensor" in WSN?
Thanks in Advance.

a plurality of sensor nodes which are deployed at the same distance in a two-dimensional plane and have sensing areas of the same size; and
an extra sensor node which has a sensing area of a smaller size than the size of the sensor nodes to sense a gap area which is not covered by the sensing areas of the sensor nodes.
Warm Regards,
Abhinav

Using outputs in WSN-3202

Good morning,
I have a doubt. You are aware that the sensor WSN-3202 has 4 analog inputs and4 digital outputs, a doubt arises in respect of this sensor outputs.
For example, for connecting a LED (6V) to one of the outputs of the sensor, I have to do?
Best regards,

Using 4-20ma Sensor on NI WSN-3202

I have a vibration switch http://ifmefector.com/ifmus/web/dsfs!VKV021.html that I am trying to get to work in my wireless sensor network. NI only offers a voltage input node (NI WSN-3202), but the sensor is only available in 4-20ma output. The analog output is only 1 wire.
Is there a way to convert that signal to use voltage and have the WSN read it accordingly?
Thanks,
Josh

Put a precision resistor in the loop and read the voltage across the resistor. For a 5VDC voltage input, use a 250 ohm resistor.

WSN 3202: increase sensor power delay before reading?

On an NI WSN-3202, Is there any way to increase the time between activation of sensor power and the time an analog reading is taken? I presently have the devices set for 250ms, but I would like to have the power turned on a good 2-3 seconds before a reading is taken. Is there any way to facilitate this, perhaps through a custom firmware update?

Hi,
Thank you for the reply.
I use a wsn-3226. There seems that there is no option to send data with radio message.
Here a print screen of my sequence, it is fairly simple, I don't understand why it's getting stuck in always on power.
I also tried to change the power setting with a user message and it worked. But it is unpracticable, I really need that to work. I use sensor that need to be power up at least 2 sec before sampling.
Thank you
Mathieu

Intrusion Detection System for Wireless Sensor Networks (IDS for WSN)

Hello,
Does anyone know how i can make an IDS for a WSN, using a Labview application or any other available application ?
I don't know how to start, analyzing timestamps ? ARP ?
Thank you

Kaoutar,
If you are only worried about other nodes trying to communicate with your gateway I dont think you should have any issue. In order to communicate between a node and a gateway the node needs to be added to the gateway see step 1 in the following KB http://digital.ni.com/public.nsf/allkb/88B2957808343185862575EC00120872. So unless you add the node it will not communicate with your gateway. Is this all that you are concerned about? If so I think you should also check out this example.
Let me know if this is not correct.

Acquiring data from all the analog channels of NI-3202 NODE using a single sensor

Hi all,
I would like to know that can i be able to get the data from all the four analog channels of NI-WSN node 3202(analog input node) connecting only single sensor on the analog input and connecting all the remaining analog inputs using wires and also shorting the ground pins corresponding to each analog input pin.
By configuring the each channels like 0.5 sec delay for every analog channels to acquire data. can we get the sensor data from all the channels by doing this. basically here i am trying to increase the minimum sampling rate of the ni-wsn NODE 3202 which is 1s.
I this approach is correct or we cannot do this.
Thanks

Stefan,
In terms of differential and RSE, channels 0-8 should default to differential when using test panels. Differential needs two input channels to function correctly and these channels must be spread apart by 8 channels. (i.e channels 0 and 7 are a differential pair) Channel 13, on the other hand, will default to rse if chosen as the reading channel because there does not exist another channel that is eight away. I am not quiet sure if the virtual channels will default channel 5 into being differential but I will check into it. If it is differential as default then you may run into problems since channel 13 is utilized in both strain gauge reads.
"The second question is, if we can also use the "voltage" setting for measuring strain gauges? we did that in the past, using LabView 6.2."
If you are referring to "voltage" as acquiring a signal with custom voltage with exciation then I would reccomend using example in LabVIEW called Acq Wheatstone Bridge Samples (with Calibration). This can be found by navigating to LabVIEW's example finder and expanding Hardware Input and Output>>DAQmx>>Analog Measurements>>Strain.
I have also included some useful links that may provide more insight into the SCC modules as well. Also, what is the excitation voltage and power that your strain gauges are expecting?

WSN 1.2 NI 9792 Security: Initial Setup? Default Username and Password?

Hello,
With NI WSN 1.1, using a 9792, I can click the Set Permissions button and if none had been set it would simply ask me for a new administrator password. Now, with NI WSN 1.2, when I click on the Set Permissions button it takes me to the 9792's web interface and says "Either no one is logged in or you do not have permissions to view/edit users, groups, and permissions." When I click the Login button, a box pops up and asks me for both a username and password. I scoured the release notes, help files, and the internet and it seems there is NO documentation on how to setup the very first username/password combination nor does it state what default username/password combination there might be. I also tried a brand new 9792 straight out of the box and loaded 1.2 on it and it has the same issue. Is there something obvious that I'm missing? How does someone initially set up security on the 9792?
Solved!
Go to Solution.

Hello Garrett,
Thanks for your post!
It looks like you are needing information on how to find out the log in information of your 9792. When using NI-WSN 1.1 we allowed users to set the initial password and this is still the case for the 9791. The 9792 is a NI-WSN node gateway as well as a LabVIEW Real Time target. Its default log in information can either be found in a Knowledge Base (KB) the LabVIEW help or MAX help. Are you using LabVIEW 2009 SP1 or LabVIEW 2010?
The default user name and password is the following:
username: admin
password: <blank>

Drivers for over the air programming for labview in wireless sensor network

Hi all ,
In my earlier post, I had requested for information regarding the drivers for Wireless sensor network( WSN) in Labview. I was successfully able to configure my WSN using Labview. thanks to all for the support and help.
However I have a new querry now. I have developed a WSN testbed with more than 1 mote and more than 1 sensor. all the motes are spread out and they communicate with the base mote. the base mote is connected to the gateway and the gateway is connected to the PC where labview and moteview are installed.
Now I need to confure the motes ( ie load a software on the mote which is not connected to the PC) . Is it possible with labview ?
I mean does labview support this kind of a structure .? Say for ex i have a mote with id = 10 and that mote is one hope away from the base mote ? can i still configure that mote remotely ?
thanks!

Hey anilhk,
When you say "load the software on the mote" do you mean actually reflashing the firmware on the sensor? If so, there is currently no functionality for this in the Crossbow driver. LabVIEW is certainly capable of doing this, but in order to get the functionality, you may have to program it yourself. The Crossbow driver source code is available to view and using the programming documentation from Crossbow you could make modifications to the driver for your own use.

Hello binarystar105,
When you uploaded new firmware, did you follow the steps outlined in this article?
How Do I Upgrade the Firmware on My NI WSN Gateway?
http://digital.ni.com/public.nsf/allkb/CF6241F5F849FC7086257909008327C5?OpenDocument
Also, what firmware version do you currently have?
What version of the LabVIEW WSN Module are you working with?
If you look at the node properties from your LabVIEW Project Explorer window, can you set the sample interval from the node tab?
You may already be familiar with this material, but I found the following white paper to be extremely helpful when I started working with WSN:

LabVIEW 2011 WSN Module?

I just received a NI WSN Starter Kit and it came with LabVIEW 2010 evaluation disks and the WSN Module Pioneer 2010. On my work laptop I have recently removed LV 2010 to upgrade to 2011. The WSN Module won't install without LabVIEW 2010...
Is there a walk-around or a new version of the WSN Module for LabVIEW 2011? Or do I have to install LabVIEW 2010 again?
Thanks.

Hello GrigS,
This is Andrew Brown, an Applications Engineer from National Instruments. There is a newer version of the NI-WSN driver (1.3) that is compatible with LabVIEW 2011. You do not need to install LabVIEW 2010 again.The download page for the driver is:
NI-WSN 1.3 - NI Wireless Sensor Networks - Windows 7/Vista/XP x86
Please note the installation instructions on the page are:
Installation Instructions
Perform the following steps to install NI-WSN 1.3.0:
Install LabVIEW
Install LabVIEW Real-Time Module (required for NI 9792 and NI 9795 support)
Install NI-RIO Driver Software 4.0 or later (required for NI 9795 support)
Download and run the self-extracting executable NIWSN130.exe. This will install NI-WSN 1.3.0 and all necessary driver files.

Get User Messages on the Host PC from WSN Nodes

Hi,
I have read the "LabVIEW Wireless Sensor Network (WSN) Pioneer - Under the Hood" and try to transmit user messages from a WSN node to the host.
However, I am stuck at the WSN Get New Messages VI. I am unable to use a "Display Message to User" function or "Unbundle function" to retrieve the messages from WSN Get New Messages VI. Can anyone help me ? I have been stuck here for hours. Thank you very much !

Hi xinke,
looking at your code, I believe the issu eis that the output of the Get New Message node is an array of clusters and as such should be indexed as with a normal array before being split up with unbundle. i have attached a VI that shows this to my post.
I hope that this helps!

WSN dynamic configuration

Hi,
I'm currently developing with the NI WSN modules 3226 and the programmable gateway 9792.
I need to programmatically configure the wireless network i.e. add and and remove measurement nodes, change acquisition rate,...
I've found an example that seems to do exactly what I need:http://www.ni.com/example/31480/en/
but I miss several vi's from the "Host API" folder:
where can I download these vi's?
Best regards,

FYI, the missing Vis were part of the

Relay switch with wsn

hello
i want to control the air condioni AC with a relay circuit to switch it on and off by WSN (wireless sensor network), i want to send a digital output to the node and then from the node to digital to analog conversion circuit then te analog output to the switch circuit which will be a relay based, so is this possible to do or not ?

If you want to use digital output wirelessly I would reccomend using WLS instead of WSN nodes. WSN nodes are more for sampling data, than for controlling things.

NI wsn nodes programmable using nesC?

Anybody, Can you please tell me whether the NI Wireless sensor networks be programmed using NesC (Tiny OS)? If so how?
Solved!
Go to Solution.

Hi cranian,
No, as you said, NesC is used to program WSN nodes that are running TinyOS. NI WSN nodes are not running TinyOS, but a firmware image optimized for measurements and long term battery life.
Using LabVIEW WSN, you can customize this personality to add analysis and decision making. See this white paper: http://zone.ni.com/devzone/cda/tut/p/id/9006
If you have existing algorithms written in C, you can place your C code directly inline with your LabVIEW code.

Wireless Sensores

Buen Día,
Estoy interesado en trabajar con el Wireless Sensor Network (WSN) Starter Kit (http://sine.ni.com/nips/cds/view/p/lang/es/nid/206916) y me gustaría saber si alguno ya ha trabajado previamente con el, si da algún tipo de problema y cuanta distancia es posible cubrir desde el punto en donde este el Gateway hasta los módulos Wireless.
Gracias,
Esteban Gonzalez

Hola Esteban;
El rango de distancia que se puede cubrir de los nodos al Gateway es de 300 metros en un ambiente interno y soportan temperaturas de -40 a 70°C. Las baterías duran más de dos años bajo un uso normal!! aunque también puede ser aloimentado con una fuente de corriente directa.
Es posible también ocupar los nodos como ruteadores por lo que un nodo podría estar a 500 metros del gateway si se usa un segundo nodo a 250 m como ruteador ocupando así tus nodos en una mesh o red.
Yo lo usé para un demo de control inalámbrico de un invernadero, para tomar mediciones de temperatura y humedad y abrir y cerrar valvulas, encender lámparas y ventiladores. La programación es bastante sencilla, en esta liga podras encontrar la información de como se realiza la programación del hardware y del software (100% compatible con LabVIEW).
Si los nodos se usan como tarjeta de adquisición, es decir como receptores y emisores de de información, se pueden correr programas bastante complejos. El único problema que tienen los nodos, es su velocidad de transmisión (se envían las muestras cada segundo para ahorrar batería) y en caso de que se quiera tener un programa embebido en el nodo, este tiene memoria y recursos de comunicación limitados.
También te paso un ejemplo delo uso de entradas y salidas digitales que encontre en la comunidad.
Si tienes alguna duda o quieres más información por favor avísame
