In this paper we present a design and development of a low cost system for real time monitoring of the water quality in IOT(internet of things).the system consist of several sensors is used to measuring physical and chemical parameters of the water. The parameters such as temperature, PH, turbidity, conductivity, dissolved oxygen of the water can be measured. The measured values from the sensors can be processed by the core controller. The raspberry PI B+ model can be used as a core controller. Finally, the sensor data can be viewed on internet using cloud computing. Keywords: water quality monitoring, Internet of Things, Raspberry PI B+, cloud computing. 1. Introduction Nowadays drinking water is the most precious and valuable for all the human beings, drinking water utilities faces new challenges in real-time operation. This challenge occurred because of limited water resources growing population, ageing infrastructure etc. Hence therefore there is a need of better methodologies for monitoring the water quality. Traditional methods of water quality involve the manual collection of water sample at different locations, followed by laboratory analytical techniques in order the character the water quality. Such approaches take longer time and no longer to be considered efficient [1]-[5]. Although the current methodologies analysis the physical, chemical and biological agents, it has several drawbacks: a) poor spatiotemporal coverage b) it is labor intensive and high cost (labor, operation; and equipment) c)the lack of real time water quality information to enable critical decisions for public health protection. Therefore, there is a need for continuous online water quality monitoring. The online water monitoring technologies have made a significant progress for source water surveillance and water plant operation. The use of their technologies having high cost associated with installation and calibration of a large distributed array of monitoring sensors. The algorithm proposed on the new technology must be suitable for particular area and for large system is not suitable. By focusing on the above issues our paper design and develop a low cost system for real time monitoring of the water quality in IOT environment. In our design raspberry PI B+ is used as a core controller. The design system applies a specialized IOT module for accessing sensor data from core controller to the cloud. The sensor data can be viewed on the cloud using a special IP address. Additionally the IOT module also provides a Wi-Fi for viewing the data on mobile. The rest of this paper is organized as follows: In section 2, shows the relation with IOT. In Section 3, shows the overall flow diagram of the proposed method and its corresponding explanation. In Section 4 shows the experiment done and its corresponding result obtained is present. In Section 5 shows the conclusion of our proposed system. 2. In Relation with IOT The internet has changed all the human lives in past decade. The IOT becomes a foundation for connecting things, sensors and other smart technologies [6]. IOT is an extension of the internet [7].IOT gives an immediate access to information about physical objects and leads to innovative service with high efficiency and productivity. There are several important technologies related to the IOT are ubiquitous computing, RFIP, wireless sensor network, cloud computing. Cloud computing is a large-scale, low cost processing unit, which is based on IP a connection for calculation and storage .The characteristics of the cloud computing has been discussed in [8],[9],[10],[11]. The IoT application areas include home automation, water environment monitoring, and water quality monitoring etc. the water quality monitoring application involves large distributed array of monitoring sensor and a large distribution network [12], [13]. It also requires separate monitoring algorithms as reviewed in [14]. In our proposed method, we introduced a cloud computing technique for viewing sensor values on the internet. The rest of this paper is organized as follows. 3. Methodology In this section, we present the theory on real time monitoring of water quality in IoT environment. In section 3.1, the overall block diagram of the proposed method is explained. In section 3.2, each and every block of the system is explained in detail. 3.1 Overall Block Diagram The overall block diagram of the system is shown in figure 1. Paper ID: SUB152064 879
