description The utility model provides a wireless cognitive sensor node based on CC430 and CC2500. The node employs a CC430F5137 single-chip microcomputer from the TI Corporation as a processor, employs a CC1101 radio frequency chip disposed on the CC430 and an external CC25000 chip as a wireless radio frequency module. The frequency of the node covers the frequency bands: ISM433/868/915MHz and 2.4G, and the hardware connection graph of the node is shown in Figure 1. The node can detect whether a set channel is spare or not. If the set channel is spare, data is transmitted to a receiving node; if the set channel is occupied, the set channel is switched to another channel for transmission. The node achieves the dynamic adjustment of communication parameters: carrier frequency, transmission power and modulation mode. Through the combination of a proper frequency spectrum detection algorithm, the cognitive function of the node is achieved. A liquid crystal display module displays the condition of a current channel in real time. A power module supplies power to all modules.
