Emergency communication is a vital component of community safety, particularly at the barangay level where timely warnings can significantly reduce risks during disasters and other emergency situations. Despite the availability of national and regional alerting mechanisms, many local communities experience delayed, unreliable, or inaccessible emergency notifications due to centralized systems, infrastructure limitations, and lack of localized control, highlighting the need for a reliable, cost-effective, and easily deployable community-based emergency notification system. This capstone study focuses on the design and development of an IoT-based Community Emergency Notification System that integrates a web application, mobile application, and an ESP32-controlled siren alarm, with the primary objective of improving emergency preparedness and response by enabling authorized users to activate verified emergency alerts remotely while maintaining a manual backup mechanism at the local level. The system utilizes an ESP32 microcontroller with internet connectivity interfaced with the Blynk Console as a virtual pushbutton, supported by a physical pushbutton override, and a web-based platform for real-time monitoring and reporting. The system was developed and tested in terms of functionality, reliability, response time, and distance capability. Results indicate that it can handle multiple concurrent activations without failure while delivering rapid response for both virtual and manual alarm triggering. Distance testing further revealed that siren audibility is influenced by environmental and structural conditions, resulting in reduced effectiveness in areas with high noise interference. Overall, the study concludes that the proposed system is a practical and scalable solution that enhances barangay-level emergency communication and contributes to improved community safety.
