Data loggers are devices that periodically take a sensor reading and then store the time-stamped sensor data to on-board memory. At a later time, the data is downloaded to a computer for analysis.
Phase IV offers several data loggers with a wireless RFID interface. A computer is connected to a RFID reader – and the reader communicates with the data logger to download data and control how the data logger collects data (start time, stop time, sampling interval…). The RFID interface is very advantageous over other non-RFID data loggers because no battery power is required for the data logger to transmit data or commands to the PC. Because RFID data loggers do not use any battery power to transmit data, they use batteries that are much much smaller than active wireless data loggers. We leverage our expertise with RFID sensing to create several versions of the world’s smallest sealed data loggers.
