DEVELOPMENT OF A WIRELESS ATMOSPHERIC PROBE FOR ENVIRONMENTAL CHEAP STUDIES
Keywords:Environmental monitoring. Real-time systems. Sensory platform. Embedded systems.
AbstractThis paper presents the development of a wireless atmospheric probe, designed to assist long-term environmental studies with limited financial resources. The work is based on the concept of Wireless Sensor Networks in which multiple sensors are arranged spatially in a particular region. Facilitating the monitoring of large areas without the need for large physical structures of communication and power, as cables and towers. The prototype, built with cheap material, captures temperature data, pressure and humidity, transmitting this information in real time to a remote receiver via radio frequency to a distance of 1 km. The prototype is also equipped with a photovoltaic system capable of guaranteeing energy independence, an essential factor for long-term studies. To evaluate the efficiency of the prototype, correlation tests were performed with a Metpak station II (Gill Instruments), to simulate the continuous operation of the sensors in situ. The tests show significant correlations between atmospheric pressure variables (98%), relative humidity (87%) and air temperature (97%). The tests ensure a good degree of reliability to the prototype; can serve as an alternative to environmental monitoring projects and Wireless Sensor Networks.

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
