SMART WATER NETWORK MONITORING: A CASE STUDY AT UNIVERSITI TEKNOLOGI MALAYSIA

Water uses need to be measured, which is critical for evaluating water stress. The Industry 4.0 via the Internet of Things (IoT) and usage of water measurement sensor can provide real-time information on the water flow rate and water pressure, that is crucial for water monitoring and analysis. There is a need for online smart water monitoring that gives out more efficient and sustainable water uses at Universiti Teknologi Malaysia (UTM) campus. A prototype of an online smart water monitoring for UTM, which was developed based on the integration of IoT and Geographical Information System (GIS), consist of four layers; (1) physical layer; (2) network layer; (3) processing layer and, (4) application layer. The findings show that when the water flow increases, the water pressure decreases. When there is no water flow, the lowest value is 52.214 Psi, and the highest value is 60.916 Psi. The latest technology integrating the IoT-GIS for smart water monitoring has shown a very efficient way of providing real-time water parameters information, cost and time effective, and allowing for continuous water consumption analysis via the cloud computing service.

ORGANIZATION OF SURFACE WATER MONITORING IN SUMY REGION

The article presents an analysis of water monitoring organization in the Sumy region. The reform of water resources management has placed the main burden on the implementation of the state water policy and ensuring the proper ecological condition of the water basin at the regional level of management. The European approach in the field of water resources management pays attention to water monitoring, which is an integral part of the state system of environmental monitoring in Ukraine. An analysis of implementation the basin principle in the region had been conducted. There are two sub-basins in the region: Desna Sub-Basin and Middle Dnieper Sub-Basin. Within the Desna sub-basin 121 massifs of surface waters have been identified, within the middle Dnieper sub-basin 230 massifs have been identified. The analysis of monitoring data on the state of surface waters, on the organization of monitoring of transboundary watercourses is carried out. The study found that farms have a significant impact on the condition of rivers. Due to the aggravation of the political situation, monitoring of transboundary watercourses is carried out only on the territory of Ukraine. The beginning of the introduction of a new approach to monitoring in Sumy region lays the foundations for the accumulation, systematization of data on the state of surface water bodies with the subsequent possibility of analyzing the existing situation with effective management decisions to achieve "good" ecological status of river basins.

Design and Build an IoT Based Prepaid Water Usage Monitoring System and Telegram Notifications

In the boarding house the use of water for each person is different for each occupant of theboarding house. The increase in water use is not proportional to the increase in water capacity and theequalization of payments for each boarding house is different. Utilization of technology Internet ofThings (IoT) and the freechat application Telegram in the application to monitor water usageinformation for each boarding house occupant. In this study, a water monitoring device was made tomonitor information from two different platforms. The server can monitor water usage information forall residents of the boarding house. Telegram provides notification information when the water capacityof boarding houses is approaching empty from each device. Using Arduino and ESP8266 as controllersand wifi connection with the server. With this system, it is easier for the boarding house owner tomonitor the water usage of each boarding house occupant.

Proof of Concept Study of an Electrochemical Sensor for Inland Water Monitoring with a Network Approach

The technologies most suitable for monitoring the ecosystem of inland waters are image spectrometry and electrochemical sensors. The reason is that these instruments are able to ensure accuracy in the surveillance of very large areas through reliable and frequent measurements performed remotely. Electrochemical systems provide low-cost, miniaturized, reliable sensors that can be organized, when equipped with commercial on the shelf (COTS) low-power radio components implementing LoRaWAN, Sigfox or NB-IoT communications, in a dense network of sensors achieving the aforementioned requirements. In this work, a low-cost, low-size and low-noise electrochemical sensor endowed with protocols for network configuration, management and monitoring is presented. The electronic interface of the sensor allows high reproducible responses. As proof of concept for its utilization in inland water monitoring, the device has been tested for water composition analysis, bacteria identification and frequent pollutant detection: atrazine, dichloromethane and tetrachloroethene. The results are promising, and future investigations will be oriented to unlock the true potential of a general-purpose approach exploiting the continuous fusion of distributed data in each of the three considered application scenarios. A new device, with reduced power consumption and size, has been also developed and tested; this new device should be a node of a large network for inland water monitoring.

Automated Alert System for River Water Level and Water Quality Assessment using Telegram Bot API

Technology has advanced to the point that it can assist people in their daily lives. Human beings may benefit from this development in a variety of ways. Progress in river water monitoring is also one of them. There are many advantages in improving the river water monitoring system. The objective of this project is to develop an automated system for monitoring river water levels and quality with push notification features. Internet of Things (IoT) was implemented in this research by using NodeMCU as a microcontroller to connect both ultrasonic sensors and pH sensors to the Internet. An ultrasonic sensor is used to read the water level, and a pH sensor is used to read the water pH values. The results show the successful output from all of 10 time attempts to obtain more accurate test results. The results will be averaged to be analysed and concluded from the test. All the tests include testing for the accuracy of the ultrasonic sensor, the accuracy of the pH sensor, and the performance of the internet connection using integrated Wi-Fi module in NodeMCU microcontroller. The system test also shows that it performs perfectly with the requirement needed to send the real-time status of the water level, water quality and an alert to the user using the Telegram Bot API. This research can help to increase the level of awareness of the river water monitoring system. This research was done by looking at people's problems in the vicinity of the river area by producing a system tool that helps to monitor the river water in real-time status.
