Symmetron Driver developed to easily read symmetron.gr dataloggers real time  values. While the dataloggers records real time data into its SD Card, the driver can read the datalogger channel values with 1 Hz sampling rate and perform calculations like min - max value, standard deviation and averaging on each channel values. The driver support up to ten S10, S41 or S101 dataloggers.
