Web based Water level and Water Quality Monitoring System using Open-Field Server in AIT

Web based Water level and Water Quality Monitoring System using Open-Field Server in AIT

Project Title: Web based Water level and Water Quality Monitoring System using Open-Field Server in AIT
Principal Investigators: Dr Masahiko Nagai, RSGIS FoS, SET.
Area of Activity: Water and ICT, Geo-informatics.

Background and rationale:

Water body such as a moat as pond is a vital element in AIT activity. Monitoring of those water level and quality is essential for flood management and re-use of water, waste water assessment, etc. It plays a crucial role in a living laboratory system. In AIT, water body is used for control water level for flood and also irrigating the lawns and playgrounds, plants and flowers, etc. But there is no such a system that can judge the water level and water quality continuously in real time in AIT. Usually, AIT staff checks with eyes. It is necessary to develop the system to continuously monitor the level and quality of water and promptly sending out warning to AIT community. The system containing sensors which play a vital role in measuring and monitoring water level and water quality at various stages. Water quality changes over time so that we need to conduct repeated measurements to characterize the variation in water quality adequately. Sensors are used to measure physical and chemical water-quality properties at discrete time intervals at point locations, and also those sensors are usually very inexpensive. It provides a continuous record of water quality that can be processed and distributed through web application interface.


The main objective of this study is aimed to develop a dynamic field sensor system for real time monitoring of water level and water quality in AIT. Water level is measured every the sensor. Water quality is determined by the parameters like pH, turbidity, and dissolved oxygen. These parameters can be detected ever hour and every day in real time. The camera can be integrated to the above system, which takes the photo about current situation of water sources and send the photo to web application interface. Web application interface can be provided for data sharing and data visualizer can developed that all users can easily understand the data by graphs or charts.

Detailed Methodology:

This proposal takes the advantages of technologies namely “Twitter Field Server” (Open Field Server). Twitter field server is developed based on the concept of ambient field server which combining the Open Field server (i.e. employing open source hardware) and free cloud data service such as Twitter which is used to share the data effectively. In Twitter Field Server, an ultrasonic sensor will be deployed which measures the water level at a fixed point and water quality sensor used for checking the quality of water. This information will be transmitted along with GPS data to the social networking website “Twitter” via cloud-based sensor back-end service. Data from the twitter integrated in web application interface and visualized as graphical data. Overall flow of the proposal is shown in figure 1.

Time Schedule

The time schedule is shown in Table 2. The time schedule is categorized into 5 steps, hardware installation, sample data collection,



Expected outputs and impacts:

The data from the sensors will be sending to social networking site like twitter. Data will be retrieved from social networking site is text format only which can be integrated and visualized in a web application interface. The end user like Sodexo team easily gets the current situation of water level and water quality with the help of graphical visualization. The system is open to public, so that any users can easily access the data. Additional sensors can be integrated to this twitter field server system at any period of time based on the requirements at that particular time. During the time of crisis, this web application information service aims to assist the local partners such as emergency manager and public officials providing situation of water level in real time so as to access the flood risk area.

How this project will contribute to AIT: A living sustainability laboratory

Quality of water system is significant part of living laboratory. In AIT there is no such system to find the water level and water quality. The proposed system is systematic, scientific, and is a real time monitoring system. The Web application online Twitter Field Server system will help the user to access the information about water level and water quality. This facility will increases the chances of the data availability to the public domain and can act as a real-time alert system during floods. The proposed system will provide the real time water quality data which will contribute to AIT as a living sustainability laboratory. Open Field Server, as living laboratory facilities could serve as highly visible examples of sustainable homes. The Living laboratory research will contribute to other research activities and innovations by producing breakthroughs in sustainable domestic technologies that will be easy to install, user friendly and that meet environmental performance standards in real life.
