Thermistor conversion techniques
Posted: Wed Mar 26, 2025 11:34 am
Hi,
Thermistors, I will be reading in several thermistor values via a I2C Analog expander and pull up resistor.
I see there is a Thermistor Component but this seems to be only for sensors directly attached to the ADC of the PIC.
Brief reading indicate that there are two common equations for converting a Thermistor ADC value to a temp, while compensating for the non linear characteristic curve of the sensor. These are the Steinhart-Hart and B parameter Equations.
There is also the method of using a look-up table.
I dont need a high level of accuracy , what is the suggested method to use in FC?
Has anyone had good success doing something similar?
Thanks, J.
