Advisory and real time monitoring system for water level of river using Raspberry Pi

Abstract

A water level advisory and real-time monitoring system was developed and tested to major rivers in Oriental Mindoro to measure and monitor actual river stage and generate early warnings via short message services (SMS) to stakeholders for potential risks of flooding. The Input-Process-Output (IPO) model served as system guide and sensor, Raspberry Pi, web and computer file full of information server and user-friendly mobile for system development and use. The development and descriptive methods of research were used to develop the system and hardware to interpret the study results and findings. Data were obtained through onsite demonstration, interviews, research, internet and questionnaire. The developed system using Raspberry pi combined with ultrasonic sensor can measure the water level of rivers and using GSM technology its measured data can be transmitted to the web and mobile service. Database of river water level with illustrated line graph can be programmed using the transmitted data reading from the Raspberry Pi with an ultrasonic sensor. Furthermore, the data generated from the developed system device can successfully generate line graph with numerical values. Based on the tests results of ISO 9126 software product quality standard, the system was considering acceptable. The system was recommended to be established and used by locals, Provincial Disaster Risk and Reduction Management Office and Municipal Disaster Risk and Reduction Management. For isolated areas, a solar panel can be used as power source for the device to make it portable and for data transmission speed, the device can also be tested in areas with low connectivity.
