Design considerations for implementing an optimal battery management system of a wireless sensor node

Abstract

Nowadays, researchers' preferably giving more attention to the power consumption of a sensor node as it is the main criteria in all Wireless Sensor Networks (WSNs). 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. Hence the proposed research implements a novel power management system by introducing pack of two solar powered batteries and an automatic battery switching system with LabVIEW based real time data acquisition. The proposed approach avoids the frequent replacement of batteries in the sensor node about 90%. Hill stations, barren region, and unattended location may include the implemented WSN.
