The HydroNet ASV, a Small-Sized Autonomous Catamaran for Real-Time Monitoring of Water Quality: From Design to Missions at Sea
OUR PROPOSED TITLE:
RAFT FOR MONITORING SEA WATER AND OHCSAFETY SYSTEM FOR AQUATIC ANIMALUSING WIRELESS SENSOR AREA NETWORK
In many developing countries the bulk of domestic and industrial wastewater is discharged without any treatment or after primary treatment only. To care our environment and thus by our health we should keep our water clean. Continuous water quality monitoring has traditionally been an expensive and complex process. Applications for continuous water quality monitoring include environmental assessments for natural resource industries, source drinking water protection, industrial effluents compliance, stream and habitat studies, water quality research, oil spill detection, ecosystem health, and general pollution monitoring.
What is Water pollution?
Water pollution refers to the chemical, physical, biological, and radiological characteristics of water. It is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose. It is most frequently used by reference to a set of standards against which compliance can be assessed. The most common standards used to assess water quality relate to health of ecosystems, safety of human contact and drinking water.
Oceanic heat content (OHC):
OHCis the heat stored in the ocean. Oceanography and climatology are the science branches which study ocean heat content. Changes in the ocean heat content play an important role in the sea level rise, because of thermal expansion.
Plastics in the Ocean:
Solid materials, typically waste, that has found its way to the marine environment. This is called marine debris.It is known to be the cause of injuries and deaths ofnumerous marine animals and birds, either because they become entangled in it or they mistake it for prey and eat it.There are multiple kinds of marine debris that have been found; anything from Styrofoam bags and fishing line to plastic bags and rubber. No matter what the case may be, every kind of marine debris is extremely dangerous for all marine life as it is to humans.
The traditional method of water quality testing is to collect samples manually and then send them to laboratory for analysis. However, it has been unable to meet the demands of water quality monitoring today in time to time. For that we need to appoint staffs to follow the industrial activities which include environment parameter too and also that not good method due to the absence of reliability.
In our system each and every individual water meter is been grouped by an individual network called Wireless Personal Area Network (WPAN). Each unit is fixed with Ph Electrodes,proximity sensor to detect plastic and temperature sensor. A group of industries are monitored, so we go for networking. If any abnormal occurs, the server unit will send the SMS to the authorized person, with details like Ph of the water.
The researchers will adapt inexpensive, sensors to withstand the aquatic environment. They are also developing and implementing new tools that ensure real-time processing of data and that make the sensors and data-processing equipment more energy efficient. “Energy efficiency is essential to making this system cost-effective,”
The system consists of multiple sensors of water testing, single-chip microcontroller data acquisition module, information transmission module, monitoring center and other accessories. Various parameters of water quality are automatically detected under the control of single chip microcontroller all day. The single chip gets the data, and then processes and analyzes them. After that, the data are instantaneously sent to monitoring center by GSM network in the form of SMS. If the water quality is abnormal, the data will be sent to monitoring center and management’s mobile in the same way at the same time. It is convenient for management to take corresponding measures timely and be able to detect real-time situation of water quality remotely. The system has realized the automation of water quality monitoring, intelligence of data analyzing and networking of information transferring. It is characterized by advantages of shortcut, accuracy and using manpower and material resources sparingly. The system has widespread application value and can be extended and transplanted to other fields of automatic monitoring where needed.
What is Ph?
In chemistry, pH is a numeric scale used to specify the acidity or alkalinity of an aqueous solution. It is the negative of the logarithm to base 10 of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are alkaline or basic.
