(With the rapid development of network communication, wireless communication technology is increasingly widely used. Wireless sensor network is a new communication technology. The learning plan of wireless communication node is very meaningful. Wireless sensor networks are mostly used in remote environments. Therefore, the power consumption requirements are very high. The general scheme requires low cost, low power consumption and miniaturization. This scheme requires the use of low-power MSP430 microcontrollers to develop a wireless sensor network node.)
