Functional description
A temperature-dependent resistor is used for temperature sensing. The circuit contains a voltage divider where the resistance can be measured depending on the temperature. A temperature is converted using a characteristic curve specific to the sensor. An NTC resistor is installed in the temperature sensor, whose resistance value drops when the temperature increases.

The resistance changes from 167 kΩ to 150 Ω depending on temperature, which corresponds to a temperature of -40°C to 130°C.
