TMP36
Notes on tmp36 implementation in circuits and conversion to temp in F:
Pins - looking down from top, with flat facing:
------------

( Vcc Out Gnd )
----------------------------------
Tie VCC to +5V (should also work fine on 3.3v)
Output pin should be tied to analog input on Arduino.
The tmp36 part has a .5V offset (to allow reading neg. zero C temps), and a scaling factor of 10 for each degree C.
So, the temperature reading for a given voltage is:
temp(C) = (voltage * 100) - 50
To convert C to F:
F=(9/5)*C + 32
