TMP36 Precision Temperature Sensor

Mapped the output from my DHT11 to this TMP36 and the voltage curve is spot on for my project enclosure. Being able to run it at just 2.7V saved me from adding a separate regulator.

Finally got this to replace a thermistor I was fighting with, and the linear voltage output makes reading it a total breeze—just hook it up to any ADC pin and the math is straightforward. It runs happily off 3.3V without any extra parts, which is exactly what my breadboard setup needed.

The voltage output scales so cleanly with temperature that I didn't even need to calibrate it before reading the data sheet's formula. It's running flawlessly off a 3.3V rail for my environmental logger, and the low power draw is a definite bonus.
