Analyte concentration alert function for analyte sensor system
Systems, methods, and apparatuses that provide alerts based on analyte data and acceleration data. An analyte sensor may generate the analyte data. An accelerometer may generate the acceleration data. A transceiver may convert the analyte data into analyte concentration values. The transceiver may convert the acceleration data into activity information. The transceiver may generate an alert based on the analyte concentration values and activity information. The alert may be communicated to a user by a mobile medical application executed on the transceiver and/or a display device (e.g., smartphone) in communication with the transceiver. The mobile medical application may display (e.g., on a display of the display device) a plot or graph of the analyte concentration values and activity information with respect to time.
