 Open Scopy and enable the positive power supply to 5V. On the channel 1 of the oscilloscope you will see the output voltage of the sensor. Open Scopy and enable the positive power supply to 5V. On the channel 1 of the oscilloscope you will see the output voltage of the sensor.
-To obtain the value of the temperature is necessary to refer to the sensor's [[https://www.analog.com/media/en/technical-documentation/data-sheets/AD22100.pdf|datasheet]] to get the output voltage function. +To obtain the value of the temperature is necessary to refer to the sensor's [[adi>media/en/technical-documentation/data-sheets/AD22100.pdf|datasheet]] to get the output voltage function.

 The current through the resistor is the voltage read on channel 1 divided to it's resistance value. Because the resistor used is 1kΩ, the numeric value of the current is the same as the voltage but in micro amperes. The current through the resistor is the voltage read on channel 1 divided to it's resistance value.

-From the sensor's [[https://www.analog.com/media/en/technical-documentation/data-sheets/AD592.pdf|datasheet]] we know that it's output current increases with 1 µA/K and that the output at 0 °C is 273 µA. +From the sensor's [[adi>media/en/technical-documentation/data-sheets/AD592.pdf|datasheet]] we know that it's output current increases with 1 µA/K and that the output at 0 °C is 273 µA.
