Abstract
Problems related to quality (and quantity) of water in natural resources or in artificial reservoirs are frequently arising and are at the center of attention of authorities and governments around the world. Many times the monitoring is not performed in an efficient time frame and a precise manner, whereas the adoption of fast and punctual solutions would undoubtedly improve the water quality and consequently enhance the life of people. To minimize or diminish such kinds of problems, we propose an architecture for sensors installed in a robotic platform, an autonomous sail boat, able to acquire raw data relative to water quality, to process and make them available to people that might be interested in such information. The main contributions are the sensors architecture itself, which uses low cost sensors, with practical experimentation done with a prototype. Results show data collected for points in lakes and rivers in the northeast of Brazil. This embedded system is fixed in the sailboat robot with the intention to facilitate the study of water quality for long endurance missions. This robot can help monitoring water bodies in a more consistent manner. Nonetheless the system can also be used with fixed vases or buoys in strategic points.
Highlights
Water is an inorganic substance of fundamental importance for the existence of living beings.It is the most abundant constituent of living bodies, acting as a universal solvent dispersing organic and inorganic compounds and is essential to biological and chemical reactions that happens in several solutions
As technical contribution, we provide a way for having the psycho-chemical parameters being shown in real time, making data available over the Internet for bodies managers, companies, research institutes and other interested users to monitoring and mitigation in situations caused by environmental problems
A sensing platform for measuring water quality could be implemented in different ways, for example as several sensors put on vessels or on buoys at some fixed points in some part of a body of water, or even inside an UAV
Summary
Water is an inorganic substance of fundamental importance for the existence of living beings. To monitor the water of lakes, rivers, and properly, the sea is of fundamental importance for keeping life in the planet Towards this direction, as the first contribution, we propose a new hardware and software architecture of an embedded system, in order to allow having installed sensors in an autonomous sailboat (a robot [4]) for water monitoring in reservoirs, rivers, and lakes, with real-time and on-line operation. Nowadays it is not possible for a system, yet, to analyze indicators that need to be collected and analyzed by way of laboratory equipments In this sense, we believe that great scientific contribution of this work is the proposal, design and development of a physical system that can be effective applied to long endurance monitoring in autonomous way, rather than only taking a few measures in a given time instant. Some systems and related theory to all these issues are described in the
