Magnetic Sensors for Smart Infrastructure and Environmental Monitoring

Abstract

Magnetic sensors have become an essential component of modern smart infrastructure and environmental monitoring systems. These sensors are capable of detecting magnetic fields and converting them into electrical signals that can be processed for monitoring structural integrity, traffic flow, environmental conditions, and industrial operations. The integration of magnetic sensing technologies with wireless sensor networks and Internet of Things (IoT) platforms enables real-time data acquisition and intelligent decision-making. In smart cities, magnetic sensors are widely used for infrastructure health monitoring, traffic detection, pipeline inspection, and environmental data collection. Their advantages include low power consumption, high sensitivity, durability, and the ability to operate in harsh environments. This article explores the working principles of magnetic sensors, their applications in smart infrastructure and environmental monitoring, technological advancements, integration with IoT-based monitoring systems, and future research directions. The study  highlights the importance of magnetic sensing technologies in building sustainable and resilient infrastructure systems.
