I'm working on a NTC Thermistor circuit attached to a 9 Volt battery, I'm trying to read the voltage and from there convert that reading into temperature. I made a Wheatstone Bridge Circuit to help me do that. My goal is to be able to measure the voltage change with minimal fluctuations when measuring with the multimeter and have an accurate measurement.
A couple questions:
To prevent the thermistor from self heating should I add a capacitor? If so where could I place the capacitor on the breadboard?
I am using 3 (10kohm) resistors, is that a good quantity for the circuit built?
The thermistor used is NTC thermistor (NTCLE100E3) of R25= 10000 ohms and a B25/85= 3977K
Theres a formula I saw on Ametherm to calculate the Temperature, what would Rb and R0 represent? Also change in voltage for both top and bottom would the same or different? The temperature measured will be between 0ºC- 25ºC.
