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.
