gas sensor technology

Gas sensor technology detects and measures the presence of specific gases in the environment using specialized sensing materials that respond to different gases through changes in electrical properties, such as conductivity or resistance. These sensors convert the chemical interaction into an electrical signal, which is then processed to determine the gas concentration. Applications include safety monitoring, environmental analysis, and industrial processes. Advances in materials like metal oxide semiconductors, electrochemical cells, and infrared sensors have improved sensitivity, selectivity, and response time, making gas sensors effective tools for ensuring safety and assessing air quality.
