Light control application
The system demonstrates the application of wireless light control through which the user
can control the LED lamp of any active smart node (D1 of STEVAl-IFS05V1) through the
smart station.
This is just the demonstration of the wireless light control application and can be enlarged to
a wider level to control any electrical appliance.
1.6 Data
logging
The system has a data logging system which can store the data of more than one year (two
values for each parameter of each node per day). The data logging system stores the
maximum and minimum values of all the parameters of all the active smart nodes (STEVAL-
IFS015V1) and smart station (STEVAL-IFS014V1) of one day along with the time stamp.
The user can refer to the maximum and minimum value of any of the parameters of any of
the nodes of any date and the time when it happened.
It also stores the node movement data of all the nodes along with the severity level, date and
time stamp. So the user can view later which node was moved at which date and at what
time.
Similar to the node movement data, the system also stores the earthquake (simultaneous
movement of all active nodes) along with the severity level, date and time stamp.
Note:
In the present system, the earthquake severity level is not calculated and has been set to
minimum level 1.
1.7 User
interface
The system has been provided with an interactive user interface with the features described
in the following sections.
1.7.1 TFT
display
The smart station (STEVAL-IFS014V1) has been provided with a 2.4" color TFT display on
which all the data is displayed along with the various colored icons/symbols.
The smart node (STEVAl-IFS015V1) has been provided with a 122 X 32 graphical LCD
display.
1.7.2 Touchscreen
The smart station (STEVAL-IFS014V1) has a touchscreen with which the user can navigate
through the menu by just pressing the particular option displayed on the display. A beep
produced by the buzzer confirms every screen touch.
1.7.3 Buzzer
Both the smart station and node have been provided with a buzzer which is used for the
alarm conditions.
