Finally, data from input sensor and Arduino Uno microcontroller reached at the control center. BACKGROUND The Philippines is a country classified as an archipelago situated near many bodies of water. Due to its geographical location and being exposed to the Western Pacific Ocean, particularly at the center of the Pacific Typhoon Belt, it is prone to many typhoons, which generally produce heavy rains and flooding of large areas. Throughout history, the Philippines has borne witness to an average of 20 tropical cyclonesperyear,earningitsreputationasoneofthemostcyclone-pronecountriesin the world, according to the Philippine Atmospheric, Geophysical, and Astronomical ServicesAdministration(PAGASA).Thisresultsinheavycasualtiestohumanlifeand destruction to crops and properties. Recently,thetyphooncalledYagi,knownbythelocalsasEnteng,dealtalotof casualtiesinourcountry.Thetyphoonbroughtheavyrainsandfloodingthatcauseda lot of casualties, such as landslides, destruction of buildings, structures,crops,and death.TheregionsaffectedbythetyphoonareIlocosRegion,CagayanValley,Central Luzon,CALABARZON,Bicol,WesternVisayas,andEasternVisayas(PCAARRD,2024). ThetyphoonEntenghitsthehighestwindof360km/hin10minutesand480km/h in 1 minute; the flood level reached tire level, was marked as Signal No. 4, has 18 recorded deaths, and has lasted 8 days since the day it was formed on August 31, 2024.

BENEFICIARIES The following might benefit from the study: The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). This study will benefitthe PAGASA in terms of monitoring and tracking weather conditions and statistics. It provides real-time data about flood levels and rainfall count, which is essential for prevention and preparation. The National Disaster Risk Reduction and Management Council (NDRRMC). This study will help the NDRRMC, as they are in charge of preventing and reducing disasters from happening. This study may prove helpful to them as it will give them accurate information on the weather and disaster conditions which will improve their response coordination. Community. This study will benefit the community, particularly in the municipality of Pilill;, this provides valuable and convenient information for flood detection and monitoring. Households. Household owners will benefit from this study, as they will be alertedtoweatherconditions,specificallyrainfallintensityandfloodlevels,whichcan be convenient for preparation. Future Researchers. This study will serve as a valuable resource for future researchers interested in conducting a study inasimilararea.Thisstudycouldalso oversee the development of more advancedtechnologiesfordetectionandmonitoring of rain and flood. PROPOSED SOLUTION The proposed solution presented by the researchers is to develop an Hydrological Detection Technology of Rainfall and Flood with Integrated Response Information of Zonal and Zero-Latency Emergency Alert entitled HydroDRIZZLE for early detection and alerts during tropical cyclones and flood attacks. The researchers will be using a developmental research design wherein the prototype undergoes a structured process of design, testing, and improvement. The rainsensorandultrasonicsensorwilldetecttheintensityofrainfallaswellaslevelsof flooding,andtheArduinowillprocessthisdata,whichwilltriggertheSIMmoduleto send real-time SMS alerts to pre-designated contacts. Simultaneously, the DFPlayer generates an alarm sound for immediate, on-site response. Each component is evaluated under various environmental conditions to assess itseffectivenessinearly fire detection.Feedbackfromeachtestcycleinformsnecessaryadjustments,suchas optimizing the sensor's sensitivity or ensuring reliable SMS transmission. This approach ensures that the system is both functional and adaptable to different scenarios, continually improving through iterative development stages. Todeveloptheprototype,theresearcherwillutilisethefollowingparts:Arduino Uno R3, GSM SimModule800L, DFPlayer Mini, rain sensors,ultrasonicsensors,and speakers. The system will be carefully assembled by connecting the Rain and Ultrasonic sensors, SIM module, and DFPlayer to theArduino,witheachconnection made according to datasheets to ensure proper functionality. The system was then powered using an external power source. The Rain and Ultrasonic sensors were programmed to detect rainfall intensity and flood levels; the SIM module was configured to send SMS alerts to a designated number, andtheDFPlayerwassetto trigger audio warnings. Using the Arduino IDE, code was written to continuously monitorthetwosensors.Theresearcherswillcreateanalgorithmthatwillbesuitable for the system. Once the system will be built, testing will be conducted to measure how quickly it could detect rainfall intensity and flood levels as well as send SMS alerts.Followingtesting,furtherfine-tuningwillbecarriedouttoimprovethesystem's responsiveness and reliability.
