A method, an apparatus, and a system for transmitting brainwave data. The method comprises the following steps: a client receiving a brainwave data value sent by a brainwave detector, and receiving a set brainwave data value sent from a serving end; the client calculating the number of brainwave data values greater than the set brainwave data value within a set time period; and the client sending the number to the serving end. The method for transmitting brainwave data can greatly save data traffic for a client, and especially in a case where multiple clients perform data transmission with a server, can greatly reduce a transmission amount of network data between the clients and a serving end, thereby enhancing stability of the serving end and robustness of data.
