Hello,
I'm a master student Engineering, and for a project, I've got next situation.
I have a room (100x400m) where the temperature and humidity (6 sensors) have to be measured.
It has to be possible to show the graphics in Labview, and has to be connected by intranet (TCP/IP)
For the cheapest sollution, I tought;
- use 6 digital temperature/humidity sensors.
- the NI USB 6501 I/O
- connect the usb to the central computer at the shop
- use labview to sent it over TCP/IP
does anyone can tell me if this is possible? Is it ok to use cheap sensors?
Yes, you can do this. You will need an application running on the central computer that will acquire data and also allow clients to connect to it, if you want the data to be sent out over TCP/IP. There is an example of a server handling multiple TCP client connections that ships with LabVIEW. You can use that as a starting point. You will then need a second application (the client) that other users would have on their computers in order to receive and display data.
As for question number 2, you will have to tell us. Price doesn't necessarily indicate accuracy (although usually more accurate is more expensive). Make sure you know the accuracy you need, then you can find multiple sensors that meet that requirement and pick the one that seems like a fair price to you.
