Abstract The internet of things (IoT), an emerging technological marvel, consists of a group of physical objects such as vehicles, machines and sensors to monitor and transfer data over the internet with much less human to machine interaction. It relies on a host of technologies like application programming interfaces (API), which in turn, help the devices to get connected with the internet. Efficient irrigation tank management requires a strong database on continuous water level dynamics for irrigation decision-making. Real-time tank water level monitoring is possible through an IoT device by integrating sensors and microcontroller that can send the water level data to the cloud. Google sheet is used to store the water level data that can be viewed using a web application as well as a mobile application. The contour map of the study tank is used to develop the stage (water level) vs volume curve. The volume of water present in the tank at any time can be arrived at for any tank water level using the above curve. The developed device can provide real-time continuous water level data with low cost and simple infrastructure, thus aiding tank water management.

AbstractWithin the U.S. Integrated Ocean Observing System Program, the Quality Assurance/Quality Control of Real-Time Oceanographic Data (QARTOD) Project develops manuals that describe variable-specific quality control (QC) tests for operational use. The QARTOD's Manual for Real-Time Quality Control of Water Level Data: A Guide to Quality Control and Quality Assurance for Water Level Observations was created with broad support from entities engaged in operational observations of water levels. The process used to generate this manual and all other QARTOD manuals exemplifies the integration of “federal, state, and local government agencies as well as the private and nonprofit sectors” described by the Hampton Roads Sea Level Rise Preparedness and Resilience Intergovernmental Pilot Project.Another project that supports Hampton Roads, Virginia, sea level rise and utilizes multiple partners is the deployment of continuous global positioning system (cGPS) receivers directly on water level sensors. These cGPS installations enable the determination of absolute sea level rise and local land subsidence. Successful transition of cGPS to an operational status requires the application of real-time data QC.

Abstract. Flood forecasting models are a necessity, as they help in planning for flood events, and thus help prevent loss of lives and minimize damage. At present, artificial neural networks (ANN) have been successfully applied in river flow and water level forecasting studies. ANN requires historical data to develop a forecasting model. However, long-term historical water level data, such as hourly data, poses two crucial problems in data training. First is that the high volume of data slows the computation process. Second is that data training reaches its optimal performance within a few cycles of data training, due to there being a high volume of normal water level data in the data training, while the forecasting performance for high water level events is still poor. In this study, the zoning matching approach (ZMA) is used in ANN to accurately monitor flood events in real time by focusing the development of the forecasting model on high water level zones. ZMA is a trial and error approach, where several training datasets using high water level data are tested to find the best training dataset for forecasting high water level events. The advantage of ZMA is that relevant knowledge of water level patterns in historical records is used. Importantly, the forecasting model developed based on ZMA successfully achieves high accuracy forecasting results at 1 to 3 h ahead and satisfactory performance results at 6 h. Seven performance measures are adopted in this study to describe the accuracy and reliability of the forecasting model developed.

ABSTRAKPada studi ini diimplementasikan sebuah sistem untuk memantau ketinggian air di dalam drum secara online real-time menggunakan platform Internet of Things (IoT). Sistem ini terdiri dari sensor ultrasonik untuk estimasi ketinggian air, kemudian data tersebut dikirim ke firebase cloud database, untuk diakses oleh perangkat monitoring atau mengakses halaman website. Level air yang tersisa direpresentasikan dalam nilai persen (%). Rata-rata kesalahan pembacaan sensor adalah tidak lebih dari 2%. Delay pengiriman yang digenerate adalah 39,06 ms, sesuai dengan rekomendasi ITU-T untuk komunikasi real-time. Sistem informasi web dapat menampilkan data ketinggian air dalam bentuk numerik dan grafik. Sistem ini telah diterapkan di sekolah menengah pertama Al-Azhar kota Bandung dan diharapkan dapat diperluas penerapannya.Kata kunci: drum, ketinggian air, real-time, IoT ABSTRACTIn this study, a real-time online monitoring of the water level in the drum was implemented using the internet of things (IoT) platform. This system consists of ultrasonic sensors to estimate the water level, then the data is sent to the Firebase cloud database, to be accessed by monitoring devices or accessing a website page. Water level is represented as a percent (%). The average sensor reading error is not more than 2%. The generated delivery delay is 39.06 ms, according to ITU-T recommendations for real-time communication. The web information system can display water level data in numerical and graphic form.

Fresh water generator is one of the most important auxiliary aircraft on ships to produce fresh water. The efficient use of fresh water can extend the life of the fresh water generator and save electricity usage. Efficient use of fresh water can be done by remotely monitoring the level of fresh water in the tank in real time.The system for knowing the water level in real time is built with an ultrasonic sensor to transmit data to the Wemos in the form of height data. Wemos converts freshwater level data into the volume of water in the tank. The volume and water level data is then displayed on the LCD and the Wemos sends data on the volume of fresh water to the internet in the form of a website with a design that is easy to understand (user friendly) and the website can be accessed anywhere. It can be seen that the system can work properly because the highest error reading is only 5%, namely in 4 liters with a tilt position og 20 right . Meanwhile, the biggest difference between sendor readings and real when testing 5 liters with a slope of 30 to the right is 0.23 liters. The best average result occur when testing flat conutions.
