What is a Gas Sensor?
Gas sensors detect the presence or concentration of gases. Depending on the gas, the sensor measures a change in heat, infrared absorption, a chemical change, or ionization when exposed to the target gas. The concentration measured produces a corresponding change measured as an output voltage.
Gas Sensor Applications
Gas detection monitoring has always been connected with the protection of individuals working in hazardous environments where the presence of dangerous gases can be found. Our technologies can be found across indoor air quality, medical, industrial, agriculture, and modified atmosphere packaging industries.
