TGS2602 Air Contaminants Gas Sensor (VOC, Ammonia & Hydrogen Sulfide Gas Sensor)

The TGS2602 Air Contaminants Gas Sensor is a high-sensitivity metal oxide semiconductor (MOS) gas sensor designed for detecting volatile organic compounds (VOCs), ammonia (NH₃), and hydrogen sulfide (H₂S) at low concentration levels. It utilizes a heated metal oxide sensing element whose electrical resistance changes in the presence of target gases, enabling accurate air quality monitoring, odor detection, and environmental sensing.

The TGS2602 is widely used in indoor air quality monitors, air purifiers, odor detection systems, industrial monitoring equipment, and embedded electronics. Its excellent sensitivity to low-level contaminants, fast response, stable output, and long operational life make it an ideal sensor for continuous environmental monitoring applications.
