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
