Data conversion formula

The TMP36 has an internal electrical circuit that produces a voltage output that is linear with the temperature. Given the voltage output, the temperature in Celsius is

$$T\ (^\circ \mathrm{C}) = 100( V - 0.5 );$$

where $V$ is in volt.

Wiring Schematics

The following schematic shows how to connect a TMP36 sensor to pin #9 of a Circuit Playground.

Note that the Vout signal can be connected to any of the four analog input pins on the Circuit Playground (pin #9, #10, #6 or #12). Refer to this web page for more information on connecting sensors to a Circuit Playground.
