I am looking to pick up the PIC-MAXI-WEB, but I can't figure out what thermistor is on there (I want to make sure it will work for my application). The schematic doesn't call out a part number for me to look up a datasheet for. Does anyone know what part that is?
It is NTC103 10k. The B parameter is 4100.
There is plenty of info about such thermistors if you search the web. The part of the code responsible for the measurement is the blow one:
r = ((1024.0*10000.0)/(float)tmp)-10000.0;
// B parameter equation - B = 4100
temperature = 4100.0/log(r/0.0111182) - 273.15;
We had to improvise with the B parameter equation a bit (http://en.wikipedia.org/wiki/Thermistor) because the board was using too much memory initially.
Awesome, thanks so much!
