Available in PDF, EPUB and Kindle. Book excerpt: The objective of the program was to design and develop a compact airborne CO2 sensor unit capable of sensing and measuring the CO2 content of manned, sealed environments. A prototype carbon dioxide sensor was designed, built, and calibrated. The sensor operates by alternately comparing the infrared absorption of the air sample at 4.26 microns, where CO2 exhibits strong absorption and at 3.90 microns where it has little absorption. A two color rotating filter provides sampling 200 times per second. The unit weighs 10 pounds and has a power consumption of 70 watts. The instrument is capable of detecting a concentration of at least 0.30% CO2 and has full scale capability to 5%. (Author).
Book Synopsis Sensors for Environment, Health and Security by : M.-I. Baraton
Download or read book Sensors for Environment, Health and Security written by M.-I. Baraton and published by Springer Science & Business Media. This book was released on 2008-11-25 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Study Institute on “Sensors for Environment, Health and Security: Advanced Materials and Technology” was held in Vichy (France) on September 16–27, 2007 where more than 65 participants, ranging from Ph. D. students to experienced senior scientists, met and exchanged ideas and know-how in a friendly atmosphere. The present book intends to cover the main topics of this NATO ASI through 32 chapters distributed over two parts (Part I: “Materials and Technologies” and Part II: “Applications to Environment, Health and Security”). The scientific programme of the NATO ASI consisted in 28 1-hour lectures given by 14 invited lecturers, 5 additional 1-hour lectures given by seminar speakers, 22 oral presentations by selected ASI participants and a poster session. The programme was divided into four sessions: (1) Advanced materials and technologies; (2) Sensors for environment; (3) Sensors for health; (4) Sensors for security. During the “Advanced Materials and Technologies” session (Part I of the present book), the lectures were dedicated to critical analyses of current methods for the synthesis of materials, nanomaterials (nanoparticles, nanowires, nanotubes, ...) and nanocomposites to be used for the fabrication of sensing devices, mainly semiconductor sensors. Among the synthesis methods, chemical (sol-gel, etc. ) and physical methods (laser deposition, DC magnetron sputtering, etc. ) were discussed. Several lectures addressed characterization techniques and it was concluded that the physical and chemical control of the materials/nanomaterials, including surface chemistry, remains a key issue for the reproducibility of the final device.
Book Synopsis Electrochemical Carbon Dioxide Sensor by : Frank B. Leitz
Download or read book Electrochemical Carbon Dioxide Sensor written by Frank B. Leitz and published by . This book was released on 1967 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the program was to develop a novel carbon dioxide sensor based on obtaining changes in the electrical resistance of anion-exchange resin proportional to the ambient partial pressure of carbon dioxide. The change in resistance is due to the increased ionization of a weakly ionized base in the presence of a sightly acid gas. A laboratory program was conducted to evaluate the response of various types of weak-base ion-exchange polymers to carbon dioxide concentrations in the range of 0 to 4%. The optimum material consisted of a condensation polymer of resorcinol, formaldehyde and triethylenetetramine. A laboratory model of the CO2 Sensor was fabricated using these sensing elements in the form of small, thin strips. In order to minimize the effects of humidity and temperature, the model contained two sensing elements, one being a reference. A guard chamber was provided to absorb any strongly-acid gases. Electrical readout is made on a balancing potentiometer with an earphone detector. The Sensor is small (about 50 cubic inches), weighs less than 6 ounces, has a power requirement of less than 0.5 watts, and its operation is independent of gravity. (Author).
Book Synopsis A PILOT STUDY OF THE ACCURACY OF CO2 SENSORS IN COMMERCIAL BUILDINGS. by :
Download or read book A PILOT STUDY OF THE ACCURACY OF CO2 SENSORS IN COMMERCIAL BUILDINGS. written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide (CO2) sensors are often deployed in commercial buildings to obtain CO2 data that are used to automatically modulate rates of outdoor air supply. The goal is to keep ventilation rates at or above design requirements and to save energy by avoiding ventilation rates exceeding design requirements. However, there have been many anecdotal reports of poor CO2 sensor performance in actual commercial building applications. This study evaluated the accuracy of 44 CO2 sensors located in nine commercial buildings to determine if CO2 sensor performance, in practice, is generally acceptable or problematic. CO2 measurement errors varied widely and were sometimes hundreds of parts per million. Despite its small size, this study provides a strong indication that the accuracy of CO2 sensors, as they are applied and maintained in commercial buildings, is frequently less than needed to measure typical values of maximum one-hour-average indoor-outdoor CO2 concentration differences with less than a 20percent error. Thus, we conclude that there is a need for more accurate CO2 sensors and/or better sensor maintenance or calibration procedures.

Download or read book ACCURACY OF CO2 SENSORS. written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Are the carbon dioxide (CO2) sensors in your demand controlled ventilation systems sufficiently accurate? The data from these sensors are used to automatically modulate minimum rates of outdoor air ventilation. The goal is to keep ventilation rates at or above design requirements while adjusting the ventilation rate with changes in occupancy in order to save energy. Studies of energy savings from demand controlled ventilation and of the relationship of indoor CO2 concentrations with health and work performance provide a strong rationale for use of indoor CO2 data to control minimum ventilation rates1-7. However, this strategy will only be effective if, in practice, the CO2 sensors have a reasonable accuracy. The objective of this study was; therefore, to determine if CO2 sensor performance, in practice, is generally acceptable or problematic. This article provides a summary of study methods and findings? additional details are available in a paper in the proceedings of the ASHRAE IAQ?2007 Conference8.

Download or read book Long-Term, Autonomous Measurement of Atmospheric Carbon Dioxide Using an Ormosil Nanocomposite-Based Optical Sensor written by and published by . This book was released on 2005 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project is to construct a prototype carbon dioxide sensor that can be commercialized to offer a low-cost, autonomous instrument for long-term, unattended measurements. Currently, a cost-effective CO2 sensor system is not available that can perform cross-platform measurements (ground-based or airborne platforms such as balloon and unmanned aerial vehicle (UAV)) for understanding the carbon sequestration phenomenon. The CO2 sensor would support the research objectives of DOE-sponsored programs such as AmeriFlux and the North American Carbon Program (NACP). Global energy consumption is projected to rise 60% over the next 20 years and use of oil is projected to increase by approximately 40%. The combustion of coal, oil, and natural gas has increased carbon emissions globally from 1.6 billion tons in 1950 to 6.3 billion tons in 2000. This figure is expected to reach 10 billon tons by 2020. It is important to understand the fate of this excess CO2 in the global carbon cycle. The overall goal of the project is to develop an accurate and reliable optical sensor for monitoring carbon dioxide autonomously at least for one year at a point remote from the actual CO2 release site. In Phase I of this project, InnoSense LLC (ISL) demonstrated the feasibility of an ormosil-monolith based Autonomous Sensor for Atmospheric CO2 (ASAC) device. All of the Phase I objectives were successfully met.
