Sensors placed in a natural environment produce a series of analog signals when they are affected by the surroundings. The AD (Analog-to-Digital) converters change the signals into digital ones, then we can packet the digital signals and transmit them based on SMS (Short Messaging Service). In this paper, AD conversion and the transmitting of digital signals are analyzed and discussed, especially for the process of the packeting the signals. Finally, we put forward a kind of optimization grouping scheme of information, and achieved satisfactory results.
