Power Consumption for Autonomous Wireless Sensor Network Nodes

Abstract

Environmental parameter using a large number of spatially distributed wireless sensor network (WSN) nodes is an extensive illustration of advanced modern technologies, but high power requirement for WSN nodes limits the widespread deployment of these technologies. Currently, WSN nodes are extensively powered up using batteries, but the battery has limitation of lifetime, power density, and environmental concerns. Recently, Wireless Sensor Networks (WSNs) have been widespread utilized in automation. The power supply of WSNs has significant influences on their performance. This paper presents a novel power management circuit for WSNs. The proposed node needs to be able to send notifications to the utility, demanding the use of backup energy strategies. The authors of the research offered an approach that can help to use solar-based energy harvester EH as the most viable source of energy to be harvested for autonomous WSN nodes. Based on the test results, an integrated power control module parameters are developed. The novelty of the research is an approach that includes different power supply solutions in order to ensure defined signal transition quality parameters for maximum effectiveness of WSN nodes power feeding.
