TVOC Gas Sensor with PID, 0-10ppm to 0-10000ppm

TVOC sensors typically use semiconductor, photoionization (PID), or metal oxide sensors to detect the concentration of organic gases in the air. When VOCs in the air come into contact with the sensor's sensitive element, they cause a change in conductivity or current signal, which is then converted into a corresponding concentration value through circuit processing. Some high-end sensors also include temperature and humidity compensation to ensure high detection accuracy and stability under varying environmental conditions.

TVOC gas sensors are primarily used to detect total volatile organic compounds (TVCs) in the air, including common organic gases such as formaldehyde, benzene, toluene, xylene, acetone, and alcohol. These substances are often derived from paint, furniture, cleaning agents, and automobile exhaust, and pose potential health risks. By monitoring the concentration of these compounds in the air in real time, the gas sensor helps users promptly identify air quality issues, enabling them to implement effective ventilation or purification measures to improve the indoor environment.

TVOC sensors are widely used in indoor air quality monitoring, smart homes, building automation systems, automotive air purification systems, and air purifiers. In the industrial sector, the gas sensor can also be used for laboratory safety monitoring and workshop emissions testing. Because TVOC has potential health implications, with long-term exposure potentially leading to headaches, respiratory discomfort, and even chronic diseases, sensors play a vital role in air quality management in daily life and public spaces, serving as essential equipment for maintaining a healthy environment.
