Wireless Sensor Nodes of a network have some major constraints due to their limited energy, storage capacity, computing power and frequent battery replacement factor, when they meant to collect the information from an unattended location using various sensors. The modern wireless sensor networks deals with power consumption by the sensor node, communication defects, mobility of nodes, size of the sensor node and importantly cost of the sensor node. The power consumption of a sensor node as it is the main criteria in all wireless sensor networks (WSNs). Hence this proposed research implements a novelty power management system by introducing pack of two solar powered batteries and an automatic battery switching system with Lab VIEW based real time data acquisition. By implementing an Automatic Battery Switching System, a long life sensor node is designed and Lab VIEW based real time data acquisition is achieved.
