LM35DZ Precision Centigrade Temperature Sensors
The LM35DZ is a precision integrated-circuit temperature sensor, whose output voltage is linearly proportional to the Celcius (Centigrade) temperature.
The LM35DZ has an advantage over linear temperatur sensors calibrated in degrees Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain conventional Centigrade scaling.
As illustrated in the figure, a supply voltage Vs between + 4V to +20V will provide an output value that is 10mV per Centigrade degree.
(0 deg C = 0.00 V, 5 deg C = 0.05 V, 10 deg C = 0.10 V, 100 deg C = 1.00V)

This Chip gives temperature as linear multiple of output voltage.
