MIX2011 Air Quality Detection VOC Gas Sensor Using For Indoor HAVC Refrigeration
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.
Feature:
High sensitivity to air quality
Low power consumption
Long life and low cost
Fast response and recovery
High sensitivity to TVOC
Simple application circuit
Good stability
Application:
Air purifier equipment;
HAVC refrigeration;
Indoor air quality monitoring;
Intelligent integrated ceiling;
Range hood, air conditioner.
