Breadboard resistance and TMP36 sensor
First, this device is not a thermoresistor, better known as a thermistor.  It is a integrated temperature sensor that produces a voltage output.  Whatever is inside that measures the temperature is irrelevant to you, and quite unlikely to be a thermistor.

Second, it's called a schematic.

As for why you're not getting the expected reading, the obvious answer is that you forgot to connect the output of the sensor to a A/D input of the microcontroller.  You only have power and ground connected.  Hook up the second sensor just like the first, except connect its output to a different A/D input.

Another issue is that some variants of this device have a shutdown input.  Make sure that it either floats to the appropriate level, or that you tie it to the appropriate level explicitly.  The datasheet should tell you if it is OK to leave open.

Also, you are missing the bypass cap.  Put a 1 &micro;F or so ceramic cap accross the power and ground of each sensor, as physically close to the sensor with as short leads as you can manage.  I'd probably put a small chip inductor in series with the supply first, then a 10 &micro;F cap around the part.  Integrated parts like this usually have some power supply noise rejection capability, but a chip inductor and cap will clean up the power the sensor sees, and are cheap and small.
