A data transmission control method is provided to manage the power consumption of an equipped power source efficiently by enabling a sensor node based on a ubiquitous sensor network to control the transmission of data more that the needed amount. A sensor senses the surrounding environment(S301). An AD converter converts the received voltage into sensing data which are the digital value, and then transmits the converted sensing data to a controller(S302). The controller determines whether the received sensing data satisfies a predetermined critical condition(S303). If so, the controller determines whether the received sensing data is identical to the comparison sensing data(S304). If not, the controller transmits the current sensing data to an external device through a communication module(S305). |
