Principle Introduction:

Air quality gas sensor adopts multilayer thick film manufacturing technology. Conductivity of the sensor is affected by the concentration of target gas.The higher the concentration is, the higher conductivity of sensor gets.We have VOC sensors and modules, the modules we also have digital output one and level showing ones.we can also supply one-stop gas sensor solution,so just tell us your detail need,then we can send you price asap.



Good stability;
Low cost, long life;
High sensitivity to TVOC;
Simple application circuit;
Low power consumption.
