monitoring multiple temperature at the same time

[nisa^k]

Hi..
I'm nisa.really need some help on my project.i have develop this labview programming to monitor 3 temperature sensor that continuously..the file ex temp3.c is the source code file that read the temperature sensor. The file newtry3.vi is labview programming that only monitor 1 temperature..Now i'm having trouble how labview can differentiate the data coming in is from which sensor..so when i use the pattern matching at file newtry2.vi, it didnt work..

Hi Nisa,

Can you possibly give a few more details? What are you using to read the temperature sensors? Are you using a National Instruments device such as a cDAQ or DAQ card or are you using third-party equipment? Do you simply want to get synchronous acquisition from three different temperature sensors?

Thanks,

i'm using LM35 temperature sensor from a training board that included with PIC16F876A microcontroller. And yes, i just simply want to get those temperature data at the same time..

Hi nisa^k,

I just want to clarify a few things. I presume that the LM35 connects to the PIC Microcontroller and it is this microcontroller you wish to "talk" to with your PC. What software do you have available to you to carry out your development? What sort of acquisition rate do you require from these temperature sensors?

I think you are going about development the correct way. Is the issue that you are receiving no data through the serial link? Do you get any serial related errors? If you want to test whether or not your serial connection is working, I would suggest using Hyperterminal to check communication from the Microcontroller.

Hope this helps,
