Abstract
Abstract Despite being a minor part of the atmosphere's composition, the so-called greenhouse gases play a crucial role in their thermodynamics. Over the past 200 years, however, human activities have significantly altered the global carbon cycle. Thus, in the current context of global warming, quantifying, with increasingly reliable values, greenhouse gas emissions and the global carbon cycle has become one of scientists’ priorities. This study aims to develop a system for acquisition and wireless transmission of carbon dioxide data from the C-Sense, a sensor manufactured by Turner Designs. As result, a reliable, compact and versatile circuit has been developed that acts as an embedded system for monitoring CO2 concentration and partial pressure, as well as two temperature variables. Regarding the transmission of data via radio frequency, its data transmission has a range of 470 m without loss. A Python script has been implemented that stores data and generates real-time graphs for system monitoring.
Highlights
Carbon dioxide (CO2) in the atmosphere plays a fundamental role in regulating the Earth's temperature through the greenhouse effect
The circuit was designed to function as an embedded system, passing through V-Model development phases and fulfilling the requirements presented by Marwedel (2018), in order to assist the monitoring of CO2 flux on aquatic environments
Besides of being powered by a 5 V mini Universal Serial Bus cable (USB), the microcontroller can operate with a non-regulated external power supply from 6 to 20 V through a borne connector linked to pins 29 and 30, assuring autonomy in accordance with the chosen battery system
Summary
Carbon dioxide (CO2) in the atmosphere plays a fundamental role in regulating the Earth's temperature through the greenhouse effect. In the context of global warming, natural ecosystems play a key role in the annual carbon balance, as they exchange large amounts of CO2 with the atmosphere and currently compensate for approximately 4 PgCyr−1 of anthropogenic emissions. Transfers that occur between the surface of rivers and lakes with the atmosphere are an essential component for estimating the global carbon cycle. The lack of these CO2 absorption measures that occur in inland waters compromises the estimate of the CO2 balance of ecosystems (Raymond et al, 2013). The development of data acquisition approaches, to quantify greenhouse gas emissions and the global carbon cycle with increasingly reliable values, has become one of the priorities of scientists in the area (Rasera, 2010; Raymond et al, 2013)
