Inside the datasheet you can learn info like lm35, lm35 typical performance, sensor output, sensor, and temperature. Here are some excerpt from this datasheet:
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ˚ Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide typical accuracies of ± 1⁄4˚C at room temperature and ± 3⁄4˚C over a full −55 to +150˚C temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM35’s low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy.
Additionally, this datasheet contains more things like temperature sensor, response, the air temperature, the surface temperature, and circuit.
