Title Design of environmental parameters with wireless
sensor node based on MSP430
Abstract
Environmental monitoring is a typical application of wireless sensor networks. Using this sensor network, researchers can conduct on going area of interest with high accuracy data collection. In this paper, through the analysis of environmental temperature acquisition system based on user’s requirement and system requirement in wireless sensor network, and choose a short distance, low cost, low power ZigBee protocol, software written using IAR software development platform, and the design of hardware system in the center of MSP430 controller module, CC2520 wireless communication module and serial communication module using Altium Designer. Using the C language to write the computer software, realized the wireless network construction and wireless sensor network in the design of -10℃ to +49℃ temperature data acquisition system. Finally, based on the design methodology and design features of LabVIEW host computer visualization monitoring software, PC software and coordinator of serial communication, completed the acquisition to environmental parameters in real-time display function, and capable of terminal nodes the sampling frequency can be adjusted. The whole system is easy to operate, and has good scalability, high application reference value.
