Smart Infrastructure Monitoring using LoRaWAN Technology

An online monitoring system for manhole covers in a smart city environment is proposed. We have used LoRa physical layer for wireless transmission and LoRaWAN protocol for cloud connectivity. The system incorporates sensor nodes, LoRaWAN network and application at the backend. LoRaWAN based IoT has an extremely low power requirement for significant distance transmission. We have employed an accelerometer sensor to monitor the position, removal or harm of manhole covers in sewage systems. When these covers are moved or harmed, the LoRa board transmits the signal, cautioning the nearest gateway associated with The Things Network (TTN), a cloud-based open source LoRaWAN platform. The TTN sends an alarm to the support division of the civic authorities to take corrective actions. Such innovative applications can be displayed for monitoring and controlling different parameters in the smart city.
