I am designing a circuit using PT100 which shows temperature range from -200 deg to 850 deg. I have temperature - resistance chart for PT100. Using that chart, i have designed a single conditioning circuit using op-amp. The output is about 0 to 1.9V (i.e., from the chart, 0V for 18.52Ω and 1.9V for 390.48Ω), and interfaced with ADC. I am using PIC 18F2520 micro controller.
Wat formula i have to use in the software to convert the adc value to temperature.
Thanks in advance.
