The in-vehicle air quality module is a digital, low-power, miniaturized module used in automotive air conditioners. The module uses a combination of MOX semiconductor gas sensor, MEMS manufacturing process, and high-performance microprocessor to detect the air pollution level in the external environment of the car. For example, the exhaust gas emitted by the vehicle in front can be controlled to close the intake valve of the car air conditioner, so as to achieve the purpose of keeping the air in the cabin clean. This module is a high-performance sensor module made by closely combining mature detection technology with high-quality design circuits.


  • Air quality detection outside the cabin;
  • internal and external circulation control of vehicle air conditioners


  • MEMS technology, strong structure
  • Intelligent Algorithm
  • Anti-electromagnetic interference
  • LIN interface output
  • Long service life

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with UL, CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to
