How do you connect the sensor to the pic?

Hello all,

I need to read my sensor data which comes to the serial port of the PC continuously and plot them real time.
The above program do this only for a limited period of time.

When run with my sensor it gave the following error.

Warning: The input buffer was filled before the Terminator was reached.
Temperature= NaN oC

Can somebody help me to resolve this issue.

Is it ok if i increase the variable i in the following for loop to change from 0:65525(some big value)?
for i= 1 :60 %acquisition of 100 points
    
    data(i)=(str2double(fscanf((s1)))/100); %read sensor
    
    disp(sprintf('Temperature= %3.2f oC' ,data(i)))
  
end

plot(data); %plot 100 points

Also i can't understand how we are getting 100 values becaude we are chaanging i 0:60

Hoping a soon reply.

Thank you.

what kind of data is being sent by the PIC?? if hex then wats the range accepted by the matlab code, i want 2 try it out using a comp to simulate the data transmission..... im workin on a similar project but using an 89c52
