  • How clean is your local air?

    Few people know how clean the air is where they live, work, exercise or where their children go to school. Although air quality can be shown to vary significantly over short distances, air pollution is generally measured using a small number of large, expensive and high quality monitoring stations. The equipment used in these stations is very accurate and complies with measurement standards but ...

  • Application of nanocrystalline metal oxide gas sensors for air quality monitoring

    Increasing concern regarding health effects caused by air pollution, together with the limited spatial resolution achievable with conventional monitoring stations, have driven efforts to develop inexpensive metal oxide gas sensors for air quality measurements. The sensing mechanism is dependent on physicochemical reactions between adsorbed gas molecules and oxygen species on the oxide surface, ...

  • 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 ...

  • Multiple sensor fault detection and isolation of an air quality monitoring network using RBF-NLPCA model

    This paper presents a data-driven method based on non-linear principal component analysis to detect and isolate multiple sensor faults. The RBF-NLPCA model is obtained by combining a principal curve algorithm and two three-layer radial basis function (RBF) networks. The reconstruction approach for multiple sensors is proposed in the non-linear case and successfully applied for multiple sensor ...

  • Two AQMesh pods operating across Spain for over 6 years

    Whilst not the only AQMesh pods still in regular use since the product was commercially launched in 2013, two AQMesh pods are still in use in Spain and demonstrate the long life of this small sensor air quality monitoring system. Over the last six years, the two pods have been loaned by AQMesh distributor in Spain, Envirodata, to a number of customers for trials and demonstrations, as well as ...

  • MONITORING & ALERT NETWORK in response to the health problems of Sargasso algae

    Martinique has been facing a major health problem in recent years. Indeed, since 2011, the unprecedented phenomenon of massive stranding of Sargasso algae has affected the Atlantic and southern coasts of Martinique. This phenomenon is the origin of a smelling gas emanating from the putrefaction of algae, among these gases hydrogen sulfide (H2S) and ammonia (NH3). Beyond the olfactory discomfort, ...

  • What air quality in car parks?

    The quality of the air in the car parks is very variable. The main pollutants are often found above the recommended limit values, exposing the users but especially the operating personnel to health problems. This air quality varies according to three main parameters: The type of parking (overhead or underground) Traffic attendance and parking The type of ventilation (servo ...

  • CO2 vs. VOC Sensors for IAQ - What`s the Difference

    People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...
