Large demand for low-power temperature sensors with a wide range has resulted in the development of a sensor that provides an analog voltage output directly proportional to the ambient temperature. To utilize this sensor, simply connect pin 1 (located on the left) to the power supply, which should be within a range of 2.7 to 5.5V. Then, connect pin 3 (located on the right) to the ground. Finally, connect pin 2 to the analog input on your device.

Product description
Wide range, low power temperature sensor outputs an analog voltage that is proportional to the ambient temperature. To use, connect pin 1 (left) to power (between 2.7 and 5.5V), pin 3 (right) to ground, and pin 2 to analog in on your microcontroller. The voltage out is 0V at -50°C and 1.75V at 125°C. You can easily calculate the temperature from the voltage in millivolts: **Temp °C = 100*(reading in V) - 50**.
