Effective Communication System for Disaster Management Using LoRA

Disaster Management leads to address various issues like floods, cyclones, fire etc. Different regions are vulnerable to different disasters due to its geo-climatic condition and varied landscapes. Our project addresses this critical need through LoRA based simplex communication system using Arduino Uno and LoRA RA-02(433MHZ). It is designed for extremely affordable and minimal power needs. It allows victims to broadcast SOS message with GPS coordinates to stationary receiver nodes up to 10km away. By restoring basic communication, we can bridge the deadly silence between victims and rescuers when every minute counts.
