I am designing a temperature monitoring instrument using 10k NTC thermistor. I have made the Circuit design which is pretty much linear for certain range(Considering calibration ) . The issue that I face is that the ntc thermistor has 5 % resistance tolerance which can give approximately more than 1 degree offset.I want my sensor circuitry to be as accurate upto 0.3 degree celcius. As of now I am using voltage divider with 5.62 k ohm resitor in series and measuring voltage across 5.62k ohm resistor.
Please help in designing the circuit to make it accurate.
