• Technology: Expanding usage of non-dispersive infrared technology-based sensors due to their robustness and extended lifetime

  Catalytic technology is best suited for detecting combustible gases in industrial environments. This method excels in detecting combustible gases such as methane and propane, rendering it highly effective for safety measures in industrial applications. Electrochemical technology-based gas sensors utilize an electrochemical reaction initiated by the target gas to detect its presence or measure its concentration. These highly sensitive and selective sensors are ideal for monitoring low-level gas concentrations in medical, occupational safety, and environmental applications. Laser-based gas sensors are one of the newest digital gas detection technologies, using laser radiation to detect gases. The non-dispersive infrared (NDIR) gas sensor has established itself as a pivotal tool in gas detection, monitoring, and analysis due to its notable precision, longevity, and susceptibility to fewer interferences. The non-dispersive infrared (NDIR) technology is suited to detecting gases such as carbon dioxide in HVAC systems. The thermal type NDIR gas sensor operates on the principle of variation in gas concentration, impacting the heat loss from a heated filament. It is known for its elevated sensitivity to a vast array of gases, including CO, CO2, and HC gases. Their robustness and extended lifetime, compared to other sensor types, make them an ideal choice for fixed installation systems in factories, smart buildings, or households. Quantum-type NDIR sensors utilize the photoacoustic effect to detect the sound wave induced when the gas absorbs a modulated light. Specific gases, including CO2, methane, and refrigerants, can be detected with high selectivity and precision, making quantum-type NDIRs extremely proficient in their task. They are best suited for applications where short-term, high-concentration gas exposure is expected, such as in gas leak detection and air quality monitoring. A Photo ionization detector (PID) technology uses ultraviolet light to ionize gas molecules, making them detectable. The PID technology is sensitive and responds rapidly, making it an ideal choice for detecting volatile organic compounds (VOCs) and other specific gases. Semiconductor gas sensors work on the principle that the conductivity of a semiconductor changes when it comes into contact with gases. The sensing materials typically used are metal oxides, which react with the gas to cause a change in resistance.

• Gas Type: Significant demand for carbon dioxide sensors in the HVAC systems

  Ammonia is a highly reactive yet colorless gas used widely in the refrigerating and fertilizer industry, posing health and explosion risks. Carbon dioxide is a pale, odorless gas, a byproduct of fossil fuel combustion, and is current in confined spaces. Carbon monoxide is a silent killer and an odorless yet poisonous gas produced during incomplete combustion. Chlorine is a greenish-yellow gas with an irritating odor, used in water purification, bleach, and disinfectants. Hydrocarbons are compounds that possess only hydrogen and carbon, often detected in the petroleum industry or areas involved in the combustion process. Hydrogen is the most delicate and abundant element in the universe, used in fuel cells and rocket fuel. Nitrogen oxide is a pollutant gas produced from vehicle exhaust and power plants. Oxygen is vital for human life, but oxygen depletion can be a major hazard in confined spaces. The gas sensor market shows dynamic range and diversity governed by the specific requirements of various gases. Its prospective growth largely depends on the manufacturing companies' individual strides and innovations.
