Data Transmission and Optimization of Energy in Smart Campus Using LoRaWAN Industrial IoT Technology

Our idea is to build a Long-Range Wide-Area Network (LoRaWAN)-based smart campus monitoring system, in order to replace the current technology of short-range communication devices. This paper mainly focuses on transmitting the data collected from end nodes or wireless sensors like Digital Humidity Temperature Sensor–11 (DHT11), Ultrasonic Sensor, Passive Infra-Red Sensor (PIR), and Ambient Light Sensor (ALS), etc., to the network server using gateway, end nodes. The end users make use of this data for monitoring and controlling several appliances. The network interface is implemented by LoRa which solves communication failure problems and saves energy during data transmission with 100 percent accuracy. This LoRa supports moderate data rates which reduces energy consumption in turn optimizes the energy utilization in the campus. This paper explains how the sensor data is transferred from the sensor using the LoRa technology.
