Earthquake detection system based on LoRa communication technology

Pre- and post-Earthquake warning system are essential for saving living, reducing and preventing the damage of landslides. WSNs are a high-potential innovation that has been successfully implemented in many real-time applications, especially landslide monitoring. This paper proposes a low-cost earthquake warning system that can detect earthquake events and monitor the status of buildings in real-time using LoRa (long-range) technology in addition to monitoring the reliability of the communication system. The vibration sensor (sw-420) and accelerometer sensor (ADXL 345) are connected to Arduino UNO, and the data collected by Arduino are sent through the LoRa transmitter module. Then, it was received through another Arduino UNO that was equipped with a LoRa receiver module. Several cases are adopted on the Electrical Engineering Technical College site with different parameters and communication paths (LOS & NLOS) to analyze the communication reliability between transmitter and receiver sides in addition to the packet received ratio. The results showed that the system is more reliable for detecting earthquakes, especially with an LOS communication system with RSSI less than -148dBm.
