An experimental method to estimate the temperature of individual nanowires
In this paper, the authors present an effective experimental method to estimate the temperature of individual metal oxide nanowires that can be used to quantify the heating produced in conductometric or other operating conditions. The here-proposed method is based on the analysis of the recovery time of the nanowire's resistance after exposure to a gas pulse (0.5 ppm of NO2 in dry air). It is ...

Working principle and application of NO2 gas sensor
A nitrogen dioxide gas sensor is an electronic device used to detect the presence of nitrogen dioxide (NO2) gas in the environment. Nitrogen dioxide is a highly toxic gas that can cause a range of health problems when inhaled, including breathing problems, lung damage and even death. NO2 gas sensors are used in a variety of applications, including air quality monitoring, environmental monitoring ...

Electrochemical NO2 gas sensor in NOx pollution control
Background: Nitrogen dioxide gas concentration can be measured by electrochemical NO2 gas sensor. On the one hand, under certain conditions, nitrogen dioxide can combine with hydrocarbons in the air to form photochemical smog. Damage the air quality of the atmosphere environment, seriously harm people’s health, so that people rely on the air environment is polluted. Sulfur oxides and ...

Using Gas Sensors to Improve Indoor Air Quality
Introduction Indoor air quality (IAQ) is a critical factor that affects our health and well-being. Poor IAQ can lead to a range of health issues, including respiratory problems, allergies, and even more serious conditions such as asthma and lung cancer. It is therefore essential to monitor and improve IAQ, especially in indoor environments where we spend a significant amount of time, such as ...

Gas Sensors for Indoor Air Quality: Improving Health and Safety
Introduction: Indoor air quality (IAQ) is a crucial aspect of our daily lives as we spend a significant amount of time indoors. Poor IAQ can lead to various health issues, including respiratory problems, allergies, and even long-term effects. Gas sensors play a vital role in monitoring and improving IAQ by detecting and measuring harmful gases present in indoor environments. This article explores ...

Air pollution monitoring for mines: a solution for cost effective measurements
Air pollution is one of the main environmental problems to be addressed by the EU. In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO2, SO2 and NOx) concentrations in air. Many cities are not able of meeting the implemented EU ...

Continuous monitoring of the performance of a NOx reduction system using electrochemical sensors
Abstract The efficiency of a NOx removal system is continuously measured using a TüVapproved analyser coupled to a high-temperature sampling system. Both NO and NO2 are measured directly using electrochemical sensors without the need to convert NO2 to NO. It is important to measure both components separately since the ratio of NO to NO2 in stack gas is much smaller after NOx removal. The ...

Air pollution monitoring: a solution for cost effective measurements - Case study
Air pollution is one of the main environmental problems to be addressed by cities worldwide. In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO, SO2 and NOx) concentrations in ambient air. Many cities are not able of meeting ...
