How to Use TMP36?

Circuit using Tmp36 Temperature sensor

As per the TMP36 example circuit diagram shown above, the characteristics of output voltage results as 1 mV/°F but is referenced to the common ground of the circuit. Also, there is a 58 mV (58°F) offset in the output voltage.

Let’s take an example:

The output voltage of the circuit reads 18 mV if the temperature of TMP36 is -40°F environment and 315 mV at +257°F. The offset voltage refers to the difference of 58(offset value) between temperature and the output voltage.
