PUBLIC SAFETY ALERT SYSTEM USING ESP32 DEVICEWITHOUTINTERNET USING MESHTECHNOLOGY

Communication is crucial for keeping people safe, especially during emergencies like storms, workplace accidents, attacks, or extended power outages. In these situations, it is vital for police, firefighters, and everyday people to share information quickly. This helps prevent injuries and ensures that rescue efforts proceed smoothly.Unfortunately, the tools we usually rely on for communication, such as phones, the internet, and satellites, often fail when disaster strikes. Earthquakes and floods can damage towers, cut off power, and disrupt internet access, leaving people without ways to communicate when they need it most. When communication fails, the situation worsens. People receive help more slowly, and warnings may not reach them in time. This writing is about addressing this problem with a Safety Alert System. This means they do not require internet or phone companies to function. Mesh networks are becoming popular because they do not rely on a single point, can self-repair, and continue toOperate even if some parts fail. Each computer can send,receive,and relay messages,allowing information to spread without a main server or tower. This makes them ideal when traditional communication tools are unavailable.
