Sensirion is the leading manufacturer of high-quality sensors and sensor solutions for the measurement and control of humidity, and of gas and liquid flows. Founded in 1998 as a spin-off from the Swiss Federal Institute of Technology (ETH) Zurich, the company is based in Stäfa near Zurich, Switzerland, and employs people in countries such as the USA, South Korea, Japan, China, Taiwan, and Germany. The headquarters in Switzerland is responsible for research, development, and production.
Millions of Sensirion's sensor components and solutions are used all over the world, including in the automotive industry, medical technology, building technology, industrial processes, and in consumer goods. Sensirion's success is based on the innovative CMOSens® technology, which combines the sensor and analysis electronics in a single semiconductor chip. This means large unit numbers can be produced at high quality and low cost. This makes Sensirion a preferred supplier of microsensors and sensor solutions.
Sites all around the world and a seamless distribution network mean we can be local to any customer anywhere in the world in order to provide the best possible support at every stage of the project. We have a range of awards that prove we are prepared to go the extra mile for our customers. Most recently, we have received the Ernst & Young "Entrepreneur of the Year® 2010" Award, which is presented to companies that have contributed to improving the competitiveness of the Swiss economy by means of personal commitment and the willingness to take risks.
Sensirion sensor products guarantee outstanding performance and correspondingly high customer utility. They are all based on our innovative CMOSens® Technology, which enables the sensor component to be combined with the analog and digital signal processing circuitry on a tiny CMOS silicon chip. This is implemented in advanced semiconductor technology, using specific microsystem processing steps to produce the microsensor structures on specially developed and patented semiconductor parts. The resulting sensor chips enable precise and reliable sensing of the desired physical parameters, such as relative humidity, temperature, or mass flow. CMOSens® accordingly represents a guarantee of high precision, reliability, and functionality combined with cost effectiveness.
Combining the sensor with the signal processing circuitry ensures that the weak analog sensor signals can be amplified and digitized with high precision directly where they are generated, thereby making them resistant to interference. This provides the basis for the extremely high measurement accuracy of CMOSens® sensors. With the elimination of fault-prone solder joints, users also benefit from outstanding long-term stability, as has been proven by extensive field tests. Furthermore, CMOSens® Technology is based on proven and reliable standard processes used in semiconductor fabrication, which also contribute to the high reliability and reproducibility of Sensirion sensor solutions.
CMOSens® chips are intelligent microsensor systems with a high degree of integration and functionality. This is provided by analog and digital signal processing, which is integrated on the semiconductor chip along with the sensor component. Our chips are further enhanced by additional intelligence for self-tests, low-power operation, and built-in linearization, digitization and temperature compensation (the latter using an integrated temperature sensor). The present high level of functionality and intelligence results from many years of development work, as can be seen from the evolutionary stages leading up to the present chip generation:
1st generation: miniaturized sensor component
2nd generation: 1st generation plus amplifier and A/D converter
3rd generation: 2nd generation plus intelligence for linearization and temperature compensation
4th generation: 3rd generation plus memory to hold calibration data
As a standard semiconductor fabrication process, CMOS is optimized for reliable mass production. Sensors fabricated in CMOSens® Technology are based on this cost-optimized standard process, which assures customers of an optimal price/performance ratio. Merging the sensor components with the signal processing circuitry on a single small chip allows system costs and package sizes to be reduced even further compared with conventional sensors. As a result, users obtain extremely high reliability and quality at a lower price.
