6.2.3 Configuring a generic nonlinear sensor
Example: Thermistor 5 kOhm
– From sensor data sheet - resistance values over temperature:
– The sensor has a nonlinear behavior
– Use characteristic curve for linearization
– Input voltage is the ratio between pull-up resistor and thermistor
Pin
Thermistor
