Data visualization for energy optimisation in smart campus application using LoRaWAN industrial IoT technology

Remote monitoring and control of appliances or equipment at institute, city, home, or industry from a large distances with low power consumption is still a complicated task. Nowadays, some smart devices or mobile phones are being proactively used to monitor and control equipment using Internet of Things (IoT) systems. However, this system requires high power consumption and covers only short distances. This paper presents Long range wide area network (LoRaWAN) based smart campus controlling system. The proposed system contains of the transmitter, receiver and a web application. A private network server is built and connected to a LoRa gateway, which gathers information from end nodes/wireless sensors and transmits it to a network server which is, TheThingsNetwork (TTN) without the use of routers at the transmitter end. At the receiver end, the data can be used to power an end-user application/dashboard/mobile app, as well as to monitor and operate various appliances and devices. LoRa is used to implement the network interface, which solves communication failure problems and allows for energy-efficient data transmission. The LoRa smart campus platform optimizes the energy utilization of the campus.
