Automotive Market
Sensirion offers comprehensive sensor solutions for the automotive market with outstanding quality, low prices, and expert support. Using Sensirion’s proven sensor solutions, we help automotive manufacturers meet stringent emission standards in the automotive industry and reduce the vehicle's energy consumption by up to 3 percent. Our sensors set new standards in terms of comfort, safety, and energy consumption. They ensure that cabin air is always optimally regulated inside the vehicle for the driver by means of air-conditioning or climate-controlled seats. Furthermore, by determining the dew point the vehicle’s air-conditioning can be controlled to eliminate fogging of the windshields and ensure a clear view of the road ahead.
Key Applications

Anti-Fogging and Climate Control
Our humidity and temperature sensors measures relative humidity and temperature either directly at the surface of the windshield or inside the passenger cabin. Using these signals to intelligently control the air-conditioning, fogging can be prevented before the driver even becomes aware of impaired visibility.
In addition to providing clearer vision that improves safety, optimal usage of the air-conditioning system can help increase fuel economy and enhance passenger comfort.
Dew Point
Controlling the air-conditioning system by measuring humidity and temperature close to the evaporator in the HVAC system allows for an optimal control loop. Increased energy efficiency and improved humidity control inside the cabin can thus be achieved.
Air Intake
Our humidity and temperature sensors measure the relative humidity and temperature in the air intake of the engine and contribute to a reduction in fuel consumption, enable better combustion control and lead to lower emissions.
Additional Applications
- Air Quality: In-cabin & outside, Battery Management
- Fuel cell cars: Leakage, concentration, humidity, electronics safety/reliability for ADAS applications, safety & anti-fogging for LiDAR/camera systems
Ready for H2 with Sensirion
Hydrogen for Automotive Applications
Climate neutrality, sustainability and the reduction of CO2 emissions are now global trends. The decarbonization of the automotive market plays an important role, as this sector contributes significantly to CO2 emissions. Political and ecological considerations are accelerating the electrification of the automotive drive train in personal and commercial mobility.
Fuel Cells
Fuel cell electric vehicles are expected to play an important role in mobility and require sensor solutions for increased safety, energy efficiency and longevity. The sensors in the fuel cells must be able to measure H2 concentration, flow as well as leakage. Humidity and temperature control in the fuel cell stack are not less important. Sensirion's sensor technology can handle this and is thus an ideal solution for your future products.
Choose Sensirion as your technology provider to ensure you are ready for an H2 future. Thanks to our broad sensor portfolio and technology know-how, we are your ideal partner for handling the complex developments in technology and regulations.
Hydrogen will also play an important role in other industries in the future. Learn more about Sensirion's sensor solutions for hydrogen for energy storage and Distribution.

Our Expertise - Your Benefit

AEC Q100 Reliability
Our sensors for the automotive market are based on the requirements of the AEC-Q100 standard. This quality standard defines industry standards for reliability, stability, and robustness of electronic components in the automotive industry. Unlike fully encapsulated electronic components, humidity, mass flow, and differential pressure sensors face additional challenges meeting these requirements because they are constantly exposed to ambient conditions. Our sensors meet these extremely high quality expectations, and every day we strive to make them even better.

ISO/TS 16949
ISO/TS 16949 is the internationally recognized quality standard in the automotive industry. Sensirion has met this standard now for several years and is constantly spurring the improvement process. Only this way we can offer you extremely high quality even at high volumes.

Support and Customized Solutions
Ideally you involve us in your project right from the start, so that already at the concept stage you can benefit from our unique sensor expertise. Our extensive experience makes us a valuable partner who can give you expert advice in all matters. We can offer you optimum support for each project, from the initial concept through the design stage to series production.

Highest Accuracy
All our sensors feature extremely high accuracy and long-term stability (no zero drift). With humidity and temperature sensors, we are one of the few manufacturers in the world to satisfy the ever more stringent demands for under two percent standard deviation. Even with the smallest pressure differences, our differential pressure sensors demonstrate a sensitivity unmatched by membrane pressure sensors. The flow sensors have no moving parts and are thus free of any drift. Our sensors are characterized by high reproducibility and high sensitivity.

Economy of Scale
As a standard process for semiconductor manufacturing, CMOS has been optimized for reliable mass production. Through their high-volume production, sensors using CMOSens® technology based on this process enable optimum cost-effectiveness – naturally without compromising reliability nor precision.
