Energy Neutral Urban Noise Monitoring and Classification With LoRaWAN Based IoT
IEEE SENSORS(2022)
Abstract
Internet of Things (IoT) technology paves the way for novel smart city applications. Noise monitoring systems are among these applications, and they help local authorities enforce noise limits more effectively. While some monitoring systems lack easy deployment due to the requirement of physical connection to electric grid or communication network, others need high maintenance because of quick battery depletion. The latter problem becomes even more challenging for the applications with noise classification capability due to higher consumption figures. This paper presents a noise monitoring and classification (NMC) system that enables energy neutral operation using solar harvester and exploiting low power capabilities of LoRaWAN.
