Running the Console Application

The console application is intended to demonstrate the required operations when using the sensor.

any other options.

b. Second, after startup, it is a good idea to reset the sensor. This puts it in a known state. Do this by selecting (2) in the

console application.

c. Each sensor is tested at the factory to determine the variation of the sensor due to fabrication. Calibration coefficients are

stored in the device at that time for later use in calculating the correct output. These coefficient values must be read from

the device and stored in software variables before temperature measurements can be taken. Do this by selecting (3) in the

console application.

Now the sensor and the software are setup. These first three steps only need to be performed once at power up.

d. The console application option (4) reads the temperature once.

e. The console application option (5) reads the temperature 20 times at approximately two measurements per second and

displays them to the screen in real time.
