How to build an on-off tempreature controller to send to one of WSN nodes ?

[Eman sa3d]

I have the WSN packet for my SDP I want of prgrame one of the nodes to recive a logic order to see if the tempreature exceed certain limit on the Ac switch While it is below that certain level off the switch ... (of course that# depending on the tempreature sensor the packet has and i have already programe it on the labview to sence the temperature and it does work ... hopefully my question is clear 😄 << wating yr quik response ,,,

thanx

Hi Eman sa3d,

What version of LabVIEW are you working with and what WSN nodes?

I ask because sending user messages has gotten a lot easier in WSN 1.3 and the new WSN Module for LabVIEW 2011.

I'm Using LV version 2010 ...And for the WSN I think what I'm using is called NI 9792 ...??

sorry 4 that.... YES I

sorry 4 that...yes I checked it's WSN 130..So now how I can programe it to send an order to the node to check if the temp..below of greater than certain temp..to on of off the AC ??

Hi Eman sa3d,

If you are using LabVIEW 2010, it will be a little more difficult.  You will need to program the node to use one of the existing IO variables to send your message.  I sounds like you only need to send a boolean, so I would recommend "hijacking" one of those lines to send your message.

Check out this example which sends average data back over the analog variables: https://forums.ni.com/t5/Archive-TKB/WSN-Module-Programmatic-DIO-and-Running-Average/ta-p/3499616

In your case, from the host you simply need to write to a designated digital line on the module, and then on the node you need to read that digital message and make decisions based upon its value.

Have a great day,

ok now I have LV 2011 ...can you explan to me how to make it ?!
