Sniffers (chemical sensors)

Sniffers, or chemical sensors, are devices designed to detect and identify specific gases or chemicals in the environment. They work by sensing changes in their materials when exposed to certain substances, often producing an electrical signal that indicates the presence and concentration of the target chemical. These sensors are used in various applications, such as detecting air quality, monitoring industrial emissions, or ensuring safety by identifying hazardous gases. They are valuable tools for providing real-time, accurate information about chemical exposure, helping to prevent health risks and maintain safety standards.
