Abstract: This paper introduces the design and realization scheme of embedded wireless sensor network node, which is based on low power single chip MSP430F149. The node is consist of MSP430Fl49, sensors, wireless communication module and batteries. MSP430F149 makes sensors to collect the temperature, humidity and vibration signals in environment, and processes the original data, then sends the data to the neighboring nodes by wireless communication module. The processed data are sent to the server finally, and the habitat monitoring is realized.
