NFC Interface for Standalone Data Acquisition Device*

Standalone embedded monitoring devices are powered utilizing alternative sources of energy to be fully independent on the power grid. To be capable of the long horizon operation such a device need to satisfy energetic neutrality conditions. This article introduces a power energy independent measurement embedded monitoring system concept using NFC communication, profiting from a low energy efficient transmission on the side of the embedded device. The concept comprises NFC interface with a proposal of communication protocol design utilizing a non-volatile EEPROM. The measurement system is based on Kinetis FRDM-KL25Z Freedom development platform. The testing has proved that the NFC communication interface is not eligible only for configuration data recording and the wireless diagnostics. The merge between the NFC interface and EEPROM technology is suitable also for a limited measured data transfer.
