Emergency alert tracker and home safety for elderly fall prevention

My grandmother lives alone, so I set up an emergency alert tracker that connects to motion sensors around her home. If she falls or doesn't move for a while, it sends an alert to me and the neighbors. It's not just about the button she wears—it's about knowing she's safe and getting help fast when needed.
