Running the Console Application

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

a. After startup, it is a good idea to reset the sensor. This puts it in a known state. Do this by selecting (1) in the console

application.

b. 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 measurements can be taken. Do this by selecting (2) in the console

application.

Now the sensor and the software are setup and ready to use. These first two steps only need to be performed at power up.

c. The console application option (3) displays a menu that allows the user to select from the four possible humidity resolution

modes of the sensor.

d. The console application option (4) displays a menu that allows the user to select from the six possible pressure over-

sampling resolution modes of the sensor.

e. The console application option (5) reads the temperature, pressure, and relative humidity values and displays each of them

once.

f.

The console application option (6) reads the temperature, pressure, and relative humidity 20 times each at approximately

two measurement triplets per second and displays them to the screen in real time.

g. The console application option (7) computes the dew point from the last measured temperature and relative humidity

values.

h.

The console application option (8) reads the MS8607’s battery status and displays it to the console.

i.

The console application option (9) reads the MS8607’s heater status and displays it to the console.
