12.2.3 Configuring a generic nonlinear sensor
Bosch Motorsport
Channel is linked
to ANA04
Input pin Pull-up
resistor is
activated
Available measurements for channel:
Measurement label
raw_name

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
+5V
Pin
3 kOhm
