Automated Water Quality Survey and Evaluation Using an IoT Platform with Mobile Sensor Nodes Teng Li1,*, Min Xia1, Jiahong Chen1, Yuanjie Zhao2and Clarence de Silva1 Department of Mechanical Engineering, University of British Columbia, Vancouver, BC V6T 1Z4, Canada; Faculty of Science, University of British Columbia, Vancouver, BC V6T 1Z4, Canada; Received: 31 May 2017; Accepted: 24 July 2017; Published: 28 July 2017 In this survey it can understand that they have used Mobile Sensor Nodes here. Various water parameters such as flow rate, temperature, air pressure, pH value, dissolved oxygen, electrical conductivity, oxidation-reduction potential, nitrogen, phosphate, organic matter, microorganisms, can be monitored through automated sensing. In this developed platform, five sensors have implemented in each Mobile Sensor Network to measure five representative parameters. They are as Temperature sensor , pH Value sensor ,Dissolved Oxygen (DO) sensor ,   Electrica...

Wireless Sensor Networks: A survey monitoring water quality Electrical, Computer and Telecommunication Engineering Department of Botswana International University of Science and Technology Palapye Botswana 28 th April 2016   (07) With the development of the world and the changes occurring in the nature, the water resources are getting highly degraded. So the researchers have to do many investigations for monitoring the quality of water for various usages. With regarding the above survey, they have conducted the studies examining the water quality by using wireless sensor networks. These networks were relatively affordable and allowed measurements to be taken remotely in real time and with minimum human intervention. As they monitored air, forest and climatology, they were able to use wireless sensor networks. But in our project we are using wired sensor networks because we need high s...

What is pH? pH, commonly used for water measurements, is a measure of acidity and alkalinity, or the caustic and base present in a given solution. It is generally expressed with a numeric scale ranging from 0-14. The value 7 represents neutrality. The numbers on the scale increase with increasing alkalinity, while the numbers on the scale decrease with increasing acidity. Each unit of change represents a tenfold change in acidity or alkalinity. The pH value is also equal to the negative logarithm of the hydrogen-ion concentration or hydrogen-ion activity. How to use a pH sensor with Arduino How it works PH is a measure of acidity or alkalinity of a solution, the pH scale ranges from 0 to 14. The pH indicates the concentration of hydrogen [H] + ions present in certain solutions. It can accurately be quantified by a sensor that measures the potential difference between two electrodes: a reference electrode (silver / silver chloride) and a glass electrode ...

Turbidity Sensor            Analog Turbidity Sensor for Arduino The Arduino Turbidity Sensor is an electronic monitoring module that is developed to work with microcontroller platforms such as Arduino, Raspberry Pi, PIC, ARM, AVR, among others. This Arduino Turbidity Sensor is able to detect and verify the quality of the water efficiently, making the turbidity measurement, where it is possible to verify the results by means of digital or analog signal next to the corresponding pins in the accompanying electronic module. The Arduino Turbidity Sensor emits at its end an infrared light, capable of detecting particles that are suspended in water, measuring the light transmittance and the dispersion rate, which changes according to the Amount of TSS (Total Suspended Solids). So the Arduino Turbidity Sensor can applied in projects involving the monitoring of water turbidity in rivers, streams, lakes,...
