FIELD: biotechnology.
SUBSTANCE: group of inventions relates to biotechnology. Disclosed is a sensor device and a sensor kit for determining an analyte in a user's physiological environment, a method of processing a data stream with time-dependent analyte concentration in a user's physiological environment. Sensor device comprises an analytical device containing a comparator, where the comparator is configured to compare the current concentration value with the first and second threshold values. At that, the analytical device is configured to analyze the data flow of time-dependent analyte concentration, setting a dead time interval, detecting increase in concentration and exceeding its first threshold value, preparing a warning signal, suppressing the warning signal and outputting the warning signal when the concentration of the analyte exceeds the second threshold value. Sensor set comprises a sensor device and is configured to monitor the time-dependent concentration of the analyte in the physiological environment of the sensor. Method includes comparing current concentration value with first and second threshold values, setting dead time interval, detection of increase of concentration and its exceeding of the first threshold value, preparation of a warning signal, suppression of warning signal output and issuance of a warning signal when concentration of the analyte exceeds the second threshold value.
EFFECT: inventions provide higher validity of a warning signal indicating to the user the need to take measures to reduce concentration of the analyte, as well as preventing too frequent issuance of such warning signals when behavior of concentration of the analyte enables reliable postponement of the warning.
