I am looking for Humidity-Temperature Sensor which will be used with LabVIEW through NI-PXI 6220.
I do not need the high solution sensor (+/-0.5C), but an easy to use as I am new with LabVIEW. To control the temperature and humidity of a chamber by measuring current data and turn ON/OFF the heater/humidifier when needed.
Is there any example for me?
Your reccomendation is highly appreciated.

For temperature i like to use this company...http://www.thermistor.com/productsDirecTemp.html I have found that there products work very well and they come with LabVIEW drivers.

Thank you Joe,
Do you have any reccomendation for humidity sensor and coding example?

Omega has some humidity sensors which also report temperatures. I have used their humidity-only sensors which produce a 0-5 V output for 0-100% relative humidity. They have a variety of other types as well.

Another company you could try is measurement computing. We use there stuff alot also.

I have used Edgtech Dew Point Hygrometers for my work at NIOSH (National Institute of Occupational Safety and Health).
They will spit out the current temp and humidity via a serial port that can be easily sucked into a LV app.

I've used Precon Temperature Humidity Sensors. They have an analog and a serial model.

We have a few of these. You can talk to it through ethiernet. I had to reverse engineer the LabVIEW code

They calibrate nicely and they have thier own web server.
See the attaced code that talks to the sensor to get the temp humidity and dewpoint. I was going to do more but who has time to do everything. (my boss thinks I do)

here is a Ben quote just for you Tim.
The problem with being able to do everything is, you are expected to!
