A National Semiconductor application
The Type LM35 temperature sensor from National Semiconductor
is very popular for two reasons: it produces an output voltage that
is directly proportional to the measured temperature in degrees
Celsius, and it enables temperatures below zero to be measured.
A drawback of the device is, however, that in its standard application
circuit it needs to be connected to the actual measuring circuit
via a three-wire link. This drawback is neatly
