STEVAL-IPR002V2

Data logger & event logger evaluation system based on the

M24LR64E-R EEPROM

Data brief

Features

• Demonstrates the dual communication

EEPROM

• Records temperature, motion (MEMS),

humidity and light (photo diode) parameters in

a dual EEPROM

• Two operation modes:

– RFID mode for reading and writing the

EEPROM using an RFID kit (starter kit

RFID reader)

microcontroller

• Utilizes a 20 mm x 40 mm inductive antenna for

RF communication with starter kit RFID reader

• Includes a graphical user interface to evaluate

the logged information from EEPROM

• RoHS compliant

Description

The STEVAL-IPR002V2 product evaluation board

is based on the M24LR64E-R dual interface

EEPROM which targets a wide range of

applications such as industrial and medical

equipment, and consumer electronics.

are the two interfaces available with EEPROM.

This evaluation platform offers an autonomous

battery-powered RFID tag with logging capability

for recording and storing data from several

sensors that measure temperature, humidity,

vibration, free-fall, tamper and light.

The value from the various sensors is stored

within the EEPROM, and then at later stages the

logged values can be retrieved through an RFID

interface for evaluation. This data logger can be

attached to any transported article, allowing it to

be tracked throughout the supply chain, and the

data can be scanned at any point using an RFID

reader.

This system can operate in two modes: data

logger mode and event logger mode.

In data logger mode, the system reads all sensor

values once per second, and stores it in the

EEPROM. The system stops logging the data

when the allocated memory for a particular sensor

is full.

In event logger mode, the system configures the

threshold limits for each sensor. When the sense

value is outside the set threshold limits, it is stored

in the EEPROM.
