Regular water quality monitoring of water bodies is essential to ensure it is within the allowing standard limits. The development of a simple and low-cost water quality measurement device for real time monitoring using Internet of Things (IoT) technology is presented in this study. The system was developed using the open-source platform Arduino UNO model and NodeMCU board as the microcontroller and Wi-Fi connection respectively. Two sensors such as temperature and turbidity were selected to be installed in the system. The physical parameters (temperature and turbidity) of water were measured and the measured data collected are able to be viewed and monitored on the mobile phone using Mobile Application via Wi-Fi connection. Therefore, this surface water quality device has potential to be applied in real time monitoring for early pollution detection and during COVID-19 pandemic spread due to limited movement.
CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
About 1% water resources such as river, lake and ocean are utilized as water supply, irrigation and recreation for human activities. The increase of population causes these water resources polluted with rubbish, toxic wastes, agriculture fertilizer and others. The physical, chemical and biological properties of the water resources should be regularly monitored to ensure they are safe to be used. Therefore, it is important to have an efficient water quality monitoring system to monitor the water quality in a particular area.
The water monitoring activities need to be carried out periodically to minimise the exposure of pollution to community and aquatic life. The traditional methods of water quality monitor involve manual collections of water samples from different locations. Typical water quality monitoring technologies are lack of integration, involve labour-intensive, long time to set up and expensive (Banna et al., 2014). The size is large and may be difficult for transportation especially for isolated and broad monitoring areas. Furthermore, the operation of the instrument needs to be carried out by an experienced user.
The application of Internet of Things (IoT) concept brings new inventions in society such as the Radio-Frequency Identification (RFID), smart home, smart device, sensors and mobile phones. These technologies can be integrated among the device components to produce the desired product (Barbon et al., 2018). The integration of IoT and water quality monitoring system is viable and has shown promising products (Moparthi et al., 2018). Daigavane et al (2014) has successfully developed a low-cost system for real monitoring system ATMEGA 328 with Wi-Fi module. It enhances the detection system of the polluted water and helps to eliminate some drawbacks of the older version systems. This shows that the implementation of the IoT in the water quality monitoring system brings a huge advantage to the smart environmental monitoring field.
Arduino is an open-source software system that can be used to developed desired devices easily [5]. Since the Arduino microcontroller is an open-source software, thus, it is easily to be accessed and significantly reduces the developed device cost. It is also recognized as an effective approach used by the researchers to manage and control the test apparatus via an automated mechanism (Maraba et al., 2017). Cruz et al. (2019) developed an automated online monitoring system to control parameters variables (pH, temperature) of an anaerobic digestion process for biogas production as an alternative to higher monitoring cost equipment, decreasing management costs. This system assisted in the performance anaerobic digestion process to improve biogas production.
In this study, the application of Arduino platform, sensors, Liquid Crystal Display (LCD) and NodeMCU ESP8266 to develop water quality monitoring device with better features and lower price is presented. The NodeMCU ESP8266 was installed to connect the device with the Blynk App for real-time data transfer via Wi Fi connection. The validation of temperature and turbidity data for performance stability and consistency of the device was carried out by testing the device in different conditions of water quality.
1.2 STATEMENT OF THE PROBLEM
In the contemporary ecosphere, Water contamination is one of the foremost reasons for numerous categories of water-borne viruses such as dengue, cholera and malaria etc., for hominid. 40% of deceases in universal are produced by water contaminations. So, the eminence of the drinking water wants to be restrained in real time although it is provided to customers. In many company, a water treatment plant has to be shut down because polluted water flowed into the plant. The water supply company was unable to pin point the contamination source and this caused a serious water service disruption. This study was carried out build a system to solve water contamination problems.
1.3 AIM AND OBJECTIVES OF THE STUDY
The main aim of the study is to build a water quality monitoring system using arduino. The objectives of the study are:
- To build the system prototype
- To automatically monitor the quality of water this will ease the job of finding the pollution source.
- To maintain good health
1.4 SCOPE OF THE STUDY
In this project, we propose a development and extension of a real time water eminence computing structure at compact cost using Internet of Things (IoT). To figure out the parameters of the water such as temperature, pH, turbidity. The centralized arrangement obtains the monitored standards from several devices over a period of time. Through the Wi- Fi structure, the sensor output data is sent to the concerned authority for additional stages to advance the water quality.
1.5 SIGNIFICANCE OF THE STUDY
This study will serve as a means of protecting people from several diseases contacted through polluted water like cholera, typhoid, dysentery, polio, meningitis and guinea worm disease. Unclean water for washing can cause skin and infectious eye disease such as Trachoma.
1.6 METHODOLOGY
