The LM35DZ temperature sensor is made for linear measurement in degrees Celsius temperature (or Kelvin).
The sensor is made for measuring temperatures between 0°C and 100°C.
The output voltage is 250mV at 25°C and the sensor has a sensitivity of 10mV/°C.
You can use this information together with the information in the LM35 datasheet, to make a transfer function of the sensor. You may also plot this on your computer or calculator.
The generel equation for the sensor output as a function of the temperature is:
Sensor output [V] = Sensitivity [V/°C] * Temperature [°C] + Output at 0°C (Offset)
Which for the sensitivity listed above and the temperature 
in 
is:
![Sensor output [V] = 0.010 V/^\circ C \cdot (t - 25^\circ C) + 0.250V = 0.010 V/^\circ C \cdot t](https://learn.andoyaspace.no/wp-content/ql-cache/quicklatex.com-c3ff4510352c5decd204eed195ae8c0d_l3.svg "Rendered by QuickLaTeX.com")
