| dc.description.abstract | Rainfall monitoring is essential for effective water resource management; however,
traditional manual methods often result in inaccurate measurements, delayed
responses, and poor recordkeeping. This project presents an IoT-based rain amount
measuring and monitoring system that automatically detects rainfall, measures water
level, stores data in the cloud, and displays real-time information through a mobile
application. The system integrates a rain sensor and an HC-SR04 ultrasonic sensor,
controlled by an ESP-8266 NodeMCU with Wi-Fi connectivity, to transmit data to a
Firebase real-time database. An Android application developed using MIT App
Inventor enables users to monitor live rainfall data and access historical records. A
theoretical 9:1 area ratio between the rain capture surface and reservoir was applied,
and calibration experiments improved accuracy by reducing measurement error to
approximately 3%. Overall, the system provides a low-cost, reliable, and real-time
solution for automated rainfall monitoring suitable for domestic and small-scale
industrial applications. | en_US |
