The design and implementation of a switch alarm for security used in this project to prevent the number of crimes from increasing every day are presented in this document. Something must be in place to keep us safe. We're all aware of the high-end security systems available on the market, but they're not for everybody. As a result, we hope to provide a solution by constructing a cost-effective electronic device capable of detecting intruder motion and activating the alarm. The main goal of this project is to incorporate a security framework that will provide users with increased privacy, protection, and peace of mind.
