What is the correct temperature sensor data format

**yaohui** · 08-28-2007, 05:10 AM

I want DIY a temperature module, and i have write a program in my avr devevlop board to simulator the temperature sensor data.
In my program i send data "1 0011.11" , but in the RR, the lable of temp1 display as N/A
What is the correct temperature sensor data format?

The data should be sent via the serial port (set in RRConfig) at 2400,8,N,1 with the format as you've described, but it MUST be followed by carriage-return (line feed+return):

1 0011.11[0x10][0x0D]
1 0012.12[0x10][0x0D]
.
.
.

If you're only sending Line feed OR Return, it most likely won't work right.

Thanks, I have get the data correct.....

Ressurecting an old thread but what is the format for negative temperatures?

Is it
1 -0011.11[0x10][0x0D]

or

1 -011.11[0x10][0x0D]

I have been playing with gettting an Arduino to add temperature to RR and want to make sure it can sense below 0.0.

Thanks
