A New Smart Sensing System Using LoRaWAN for Environmental Monitoring

An increasing interest is drawn to environmental monitoring applications such as weather monitoring, smart city, and smart agriculture. This paper proposes a new Internet of Things (IoT) sensing system for environmental monitoring. The system consists of wireless sensor nodes, communication network, and data visualization and storage cloud. The wireless sensor node is powered by a solar panel and Radio Frequency (RF) energy harvester (in case solar energy is not available) to avoid changing batteries frequently and save the maintenance cost. It has a compact size and can sense many environmental parameters, such as temperature, air pressure, humidity, loudness, and air quality. A low power communication technology named LoRaWAN is used to connect different sensor nodes for a wide coverage area. Finally, a cloud server named Cayenne myDevice is employed to receive, present and store measured data. This smart sensing system with energy harvester can be used for many other IoT applications.
