Company information: 

Sensirion is a leading sensor manufacturer, providing relative humidity sensors and flow sensor solutions with unique performance. Together with the capacitive humidity sensor, our product range includes gas and liquid flow sensors, mass flow meter and controllers, and differential pressure sensors. With headquarters in Switzerland and sales offices in Japan, Korea and the US, Sensirion is able to optimally support its international OEM customers in respect of their individual requirements. The microsensor solutions boost the performance of OEM products in a wide variety of applications. Among others, they include gas flow regulators, building automation modules, and applications in the automotive, medical technology and consumer goods sectors. Sensirion products are distinguished by their use of patented CMOSens® technology. This enables customers to profit from intelligent system integration, including calibration and digital interfaces, which allows considerable cost savings to be achieved thanks to ease of use and modularity. The strengths of our leading technology constitute the benefits of all product categories:

Humidity and Temperature Sensors
Relative humidity sensors from Sensirion are among the world’s leading humidity and temperature sensor products. Powered by CMOSens® technology, they allow precise and reliable humidity control and measurement at low cost. Sensirion’s digital and capacitive humidity sensor is designed for diverse applications such as data logging, climate control, and antifogging.

Liquid Flow Sensors
Media isolated liquid flow sensors from Sensirion establish new standards wherever low liquid flow monitoring, liquid handling and liquid dosing are important. Our unique CMOSens® Technology allows measuring liquid flow even through diverse tubing materialsin milliliters, microliters or even nanoliters per minute. Besides our standard products, Sensirion develops and manufactures micro flow sensor modules for medical devices, life science, bio-tech, semiconductor industry and analytical instruments.

Mass Flow Meters
Sensirion’s mass flow sensors represent a new generation of cost optimized mass flow meters for gases. At an unbeatable price/performance ratio it covers a wide flow range with high accuracy. The mass flow meters are able to give a digital, linearised, calibrated and temperature compensated flow signal. It enables fast, accurate and reliable flow measurement at low cost for a wide range of standard and OEM applications.

Mass Flow Controllers
All CMOSens® mass flow controller (MFC) offer fast and accurate control of gas flow over wide ranges. The digital calibrated and temperature compensated sensor signal is converted directly on the chip into a signal which is used in the analog or digital controlling circuit to control the valve. That results in high accuracy, fast settling time and large dynamic ranges. CMOsens® mass flow controllers are highly suitable for a variety of applications like dry etching, surface coating, gas mixing, gas analysis, and many others.

Multi-Pixel Gas Sensors
The multi-pixel gas sensor platform SGP creates new possibilities for the measurement of indoor air quality. The SGP offers a complete gas sensor system integrated into a very small 2.45 × 2.45 × 0.9 mm3 DFN package featuring an I2C interface and fully calibrated air quality output signals. Sensirion’s MOXSens® Technology provides the SGP with an unmatched robustness against contamination by siloxanes resulting in unique long-term stability and accuracy. The SGP further combines multiple metal-oxide sensing elements − the pixels –  on one chip to provide more detailed air quality signals. The unprecedented combination of long-term stability and multi-pixel technology makes the SGP a perfect choice for indoor air quality monitoring in mobile, smart home and appliance applications.

Differential Pressure Sensors
Differential pressure sensors from Sensirion offer high accuracy and resolution, especially in low pressure ranges. The small and cost-effective design makes them an ideal match for price-sensitive solutions, especially in medical and HVAC applications. Reliability, speed and sensitivity have made them the first choice in new medical designs and redesigns.

Particulate Matter Sensor
With this new particulate matter sensor, Sensirion expands its range of environmental sensing solutions and opens up a new dimension in indoor and outdoor air quality applications.The MCERTS-certified SPS30 particulate matter (PM) sensor marks a new technological breakthrough in optical PM sensors. Its measurement principle is based on laser scattering and makes use of Sensirion's innovative contamination-resistance technology. This technology, together with high-quality and long-lasting components, enables precise measurements from the device's first operation and throughout its lifetime of more than ten years.

CO2 Sensor
CMOSens® Technology for IR detection enables highly accurate carbon dioxide measurement at a competitive price. Along with the NDIR measurement technology for CO2 detection, a best-in-class Sensirion humidity and temperature sensor is also integrated on the same sensor module. Ambient humidity and temperature can be outputted by Sensirion’s algorithm expertise through modeling and compensating of external heat sources without the requirement for any additional components. Thanks to the dual-channel principle for the measurement of carbon dioxide concentration, the sensor compensates for long-term drifts automatically by design. The very small module height allows easy integration into different applications.
