LM35 - Analog
Temperature Sensor
The LM35 is a low-cost precision
integrated-circuit temperature sensor,
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

using RB0 microcontroller pin. The selection of this line is done placing SW11.4
DIP switch to ON position (Figure 21-4). When placing the sensor in the socket
make sure that half-circle on the board silkscreen markings matches the rounded
part of the LM35 sensor. If you accidentally connect the sensor the other way,
it can be permanently damaged and you might need to replace it with another
one. During the readings of the sensor, make sure that no other device uses the
selected analog line, because it may interfere with the readings.

obtain convenient Centigrade scaling.
It has a linear +10.0 mV/°C scale factor
and less than 60 μA current drain. As
it draws only 60 μA from its supply, it
has very low self-heating, less than
0.1°C in still air. EasyPIC Fusion
enables you to get analog readings
from the LM35 sensor in restricted
temperature range from +2ºC to

separate socket (TS2) for
the LM35 sensor in TO-92
plastic packaging. Readings
are done with microcontroller
using single analog input line,
which is selected with DIP switch
SW11.4. Switch connects the sensor
with RB0 microcontroller pin.
