Wireless sensor network considers data as the center of the network. Sensor nodes within the region will collect surveillance information and transmit it to the server for processing and analysis. Data acquisition, hence, become especially important. In addition, the wireless sensor node contains a lot of random laid nodes and can not be managed by hand, so server must have software to manage all the nodes. The paper aims to develop a wireless sensor network node management and data acquisition software, mainly to solve the wireless network data acquisition and the orderly management of nodes. The node management based on SNMP uses get/set message to access to the node information and reset it. The data acquisition based on trap message to collect data from nodes. The data includes light value, temperature value and RSSI and so on. System test results show that the software is real-time, accurate and with high reliability.
