STEVAL-IPR002V1 Data logger and event logger based on M24LR64-R EEPROM

The STEVAL-IPR002V1 is based on the M24LR64-R, a dual interface EEPROM which targets a wide range of applications such as industrial or medical equipment and consumer electronics.

RFID (13.56 MHz) and I²C serial communication are the two interfaces available with EEPROM. This demo is an autonomous battery-powered RFID tag with logging capability for recording and storing the sensor data of the following sensors: temperature sensor, humidity sensor, vibration, freefall, tamper and light.

The value of different sensors is stored inside the EEPROM and then at later stages these logged values can be retrieved over the RFID interface

for evaluation. This data logger can be inserted along with any transported article and this article

can then 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 the sensor values once every second and stores the same inside EEPROM. The system stops logging the data when the allocated memory for a particular sensor gets filled.

In event logger mode, the system configures the threshold limits for each sensor. Whenever the sense value is outside the set threshold limits, it is stored in the EEPROM.

技术特性

Evaluation system demonstrating dual communication interfaces (RF and I²C) of M24LR64 EEPROM
Demonstration board for recording temperature, motion (MEMS), humidity and light (photo diode) parameters in a dual EEPROM M24LR64-R
Two operation modes:
- RFID mode for reading and writing the EEPROM using an RFID kit (RFID starter kit reader used)
- I²C read and write using a microcontroller (STM8L used for demonstration)
