Sensor node is a basic unit for the underwater sensor networks. Each sensor node has the following main functions, i.e., information acquisition, data processing, underwater acoustic communication, self-organizing network, etc. The sensor nodes are randomly deployed in the detection area for achieving omni bearing underwater information acquisition. However, the cost and the power consumption for the existing underwater sensor nodes are high. For solving these disadvantages, we design a kind of underwater sensor node that can be applied for the underwater communication channel with low cost and power consumption by fusing the Orthogonal Frequency Division Multiplexing (OFDM) technique and the Digital Signal Processing (DSP) technique.
