- 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 worldwide. Sensirion’s sensors are used in a wide range of markets and different applications. 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.
