What Are Gas Sensors and Why Are They Important?
Gas sensors are electronic devices designed to detect, measure, and monitor the presence and concentration of gases such as carbon monoxide, carbon dioxide, methane, ammonia, hydrogen sulfide, and volatile organic compounds (VOCs). These sensors convert chemical interactions into electrical signals, enabling real-time monitoring and automated alerts.
Their importance has increased significantly due to:
Growing concerns about air pollution and climate change
Rising demand for workplace safety systems
Expansion of smart infrastructure and IoT-based monitoring
Stricter environmental and industrial safety regulations
Industries now rely on gas sensors not only to prevent accidents but also to ensure regulatory compliance and operational efficiency.
