Chemical Sensors

Chemical sensors are devices designed to detect and measure specific chemicals in the environment, substances, or liquids. They work by responding to the presence of a target chemical through a measurable change, such as a variation in electrical signals, color, or other properties. These sensors are used in many fields, including health, safety, and environmental monitoring, to identify pollutants, detect gases, or analyze chemical compositions quickly and accurately. Essentially, they act as chemical "detectors," helping us understand and control our surroundings better.
