The Emonio X1 addon card adds storage capacity to the Emonio P3 as well as an interface for temperature sensors (DS18x) or a pulse counter.
Together with the default-installed 32GB SDhc card, the Emonio is capable of logging up to four years with a one-second precision ! (One line of CSV-file for every second.)
