The TMP36 is an easy to use temperature sensor – an excellent choice for anyone getting started with sensors and microcontrollers! Simply connect pin 1 to a power source ranging between 2.7 and 5.5VDC, pin 2 into an analog input in your microcontroller or analog to digital converter, and connect pin 3 into a ground.

The sensor works by setting a voltage on pin 2 ranging between 0 and 1.75V depending on the temperature. -50°C will result in 0V being output, while at the other end of the range, 125°C will result in 1.75V being output.
