Method and device for reporting data

Disclosed are a method and device for reporting data. The method for reporting data comprises: acquiring a plurality of pieces of data collected by at least one sensor in a wireless body area network; according to preset combinations, grouping the plurality of pieces of data, to obtain at least one data packet; judging whether data in each data packet of the at least one data packet satisfies a corresponding first preset condition; and when the corresponding first preset condition is satisfied, reporting the data in the data packet corresponding to the first preset condition. By means of the present invention, reporting all data is avoided, thereby reducing energy consumption and data traffic.
