Ensuring safety in environments where hazardous gases are present is paramount. In Australia, stringent standards govern the selection, installation, use, and maintenance of gas detection systems across various industries. Key Standards: AS/NZS 60079.29.1:2017 : This standard specifies performance requirements for detectors of flammable gases. It outlines general construction, testing, and performance criteria for portable, transportable, and fixed apparatus intended for use in potentially explosive atmospheres. AS/NZS 60079.29.2:2016 : This standard provides guidelines for the selection, installation, use, and maintenance of gas detectors for flammable gases and oxygen. It emphasizes the importance of proper placement and upkeep to ensure optimal functionality. AS/NZS 4641:2018 : Focusing on the detection of oxygen and other gases at toxic levels, this standard outlines general requirements and test methods for electrical equipment used in such detections. Industry-Specific Applicatio...

Air quality monitoring is becoming increasingly critical nowadays. The city of Paris, for instance, operates 13 measuring sites (AIRPARIF, 2018), whereas in London, air quality is monitored at around 100 locations (Greater London Authority, 2018). Although these numbers are seemingly high, they correspond to a spatial coverage of the order of one station over a few tens of square kilometers. This limitation can be lifted by employing low-cost sensors (LCSs) in dense observational networks that can enable quick and effective identification of pollution sources and determination of concentration gradients over specific areas. In Germany, e.g. in Munich, there exist only five reference stations, which are insufficient for accurately depicting a real-time pollution map for the entire city. A research study from TU Munich[Zhu et al], illustrates the importance of combining different measurement techniques to capture spatial and temporal patterns within a city and derive gas concent...

  The Science Behind Gas Sensors: How Different Types of Gas Sensors Work 👀 Gas sensors are essential devices used in various industries and environmental applications to detect and measure gases. These sensors operate on different principles depending on the type of gas being detected and the required sensitivity. In this article, we will explore the science behind four common types of gas sensors: electrochemical, solid polymer, non-dispersive infrared (NDIR), and photoionization detectors (PID). Electrochemical Gas Sensors Electrochemical gas sensors operate based on redox reactions that occur at the sensor electrodes when a target gas interacts with the electrolyte. These sensors typically consist of three electrodes: a working electrode, a counter electrode, and a reference electrode, all immersed in an electrolyte solution. When the gas diffuses through a permeable membrane and reaches the working electrode, it undergoes a chemical reaction, generating an electric current pr...

  Solid Polymer Electrolyte (SPE) Technology in Gas Sensors: A Game-Changer for Air Quality Monitoring Gas sensors play a critical role in monitoring air quality, industrial safety, and environmental protection. Among the various sensor technologies available, solid polymer electrolyte (SPE) gas sensors have emerged as a highly effective solution, offering unique advantages over traditional sensing methods. This article explores the origins, strengths, and applications of SPE technology in gas sensing. The Invention and Development of Solid Polymer Electrolyte Sensors Solid polymer electrolyte technology was first introduced in the mid-20th century as part of developments in electrochemical systems, particularly fuel cells. However, its application in gas sensing gained momentum in the 1980s and 1990s, when researchers identified its potential for detecting gases such as ozone, carbon monoxide, and nitrogen dioxide. Since then, continuous advancements have improved sensor stab...
