Thanks Skimask,

Well, if it was me, and I wanted close to 100% assurance that my data was good
I agree. Me also.

It makes perfect sense.

The reason i'm with this system it's because it was simple to build and simple to transfer the data to the PC using a freeware RS232 logger software. I just dump the values to it with the format i have showned ( one temp value per line ) saving them in a txt file and then just import to excel and generate the graphs.

The reason i'm asking how to do this with this system is that this way i can maintain my logger as is and just need to build the module with LCD to view the data "on site".

I cannot re-program the logger because it's encapsulated with resin to reduce size and weight.

If it could be done i was more than half way there to complete the module

Thanks
