System set-up
This is a 3 V coin cell operated system. Sensor values are logged inside the EEPROM and
are evaluated using the graphical user interface which retrieves the data over RF.
System prerequisites
This system has three different stages:
1. Pre-data/event logging stage
2. Data/event logging stage
3. Post data/event logging stage
The pre-data/event logging stage is used to select the mode of the system. The system can
be selected in data logger mode or event logger mode. This selection is done using the GUI.
When selected in data logger mode, all the sensors are enabled for logging every one
second.
When selected for event logger mode, the boundary limits for different sensors are
configured using the GUI. These boundary conditions are the threshold values for sensors.
When the sensor measured value is outside these values, they are logged inside the
EEPROM.
Data/event logging stage is the run-time stage of the system where sensor values are stored
inside the EEPROM.
The post data/event logging stage is the retrieval stage in which the logged values are read
by the RFID reader and evaluated on the GUI.
Therefore, the prerequisites to evaluate the data logger are the following:
● CR95HF demo board or STARTKIT-M24LR-A RFID reader
● STEVAL-IPR002V1 data logger board
● CR2032 - 3 V coin cell (MAXELL or equivalent)
● Data logger graphical user interface for connecting the RFID reader to the computer
and for the handling of the data logger board.
