Experts for Environmental and Flow Sensor Solutions

Sensirion AG, headquartered in Stäfa, Switzerland, is a world's leading manufacturer of digital microsensors and systems. The product range includes gas and liquid flow sensors, differential pressure, as well as environmental sensors for the measurement of humidity and temperature, volatile organic compounds (VOC), carbon dioxide (CO2) and particulate matter (PM2.5). With a global network of offices in USA, Europe, China, Taiwan, Japan and Korea Sensirion provides sales and technical support to our international customers. In the USA, we are headquartered in Chicago with a branch office in Palo Alto, CA. We supply standard and custom sensor system solutions for a vast range of applications including medical, industrial, automotive, analytical instruments, mobile and consumer goods, smart home, IoT, appliance and HVAC. One of the hallmark features of Sensirion products is the use of patented CMOSens® Technology which enables intelligent system integration of the sensor element, ASIC, calibration data, signal processing and digital interface on a single chip.

  • Once again, Sensirion trailblazes innovation in environmental sensing to create healthier and more productive environments. Having a proven track record in CO2 sensing, Sensirion now breaks the size barrier in CO2 sensing with the SCD40 - the first miniaturized CO2, humidity and temperature sensor that fits in a space of just one cubic centimeter. This disruptive innovation is based on the photoacoustic sensing principle and combines minimal size with maximum performance to open up numerous new integration and application possibilities.

    The increasing environmental awareness not only affects the way how people live, travel and eat, but also how buildings are designed. Modern houses strive to achieve a very high energy efficiency to save natural resources that are mainly used for heating. A consequence is the trend towards tighter buildings that are much better insulated than older homes. Even the opening of windows is not allowed or possible anymore. Tight buildings mean there is less air exchange through walls, roofs, windows, cracks etc. which eventually requires an active ventilation system to get in fresh air to provide a healthy indoor environment. In addition to that, there is various building standards and codes (e.g. WELL, LEED, ASHRAE) that focus on how an efficient ventilation system shall be designed. Humans are the main source of contamination indoors (e.g. smell, temperature, humidity (which can lead to mold), CO2, particulate levels, toxic gases, etc.) which is why the need for fresh air depends on the amount of people being present in a room and their activities (e.g. cooking, sports, resting). Based on the corresponding indoor air quality, it is possible to trigger a demand-controlled ventilation, which on one side ensures a healthy and comfortable environment and on the other side enables an energy-efficient operation. Energy-efficient in that sense means that the amount of air which is taken into the house, and eventually has to be treated (e.g. cooled, heated, filtered), is reduced to a minimum.

    PASens® Technology is based on the photoacoustic sensing principle. The photoacoustic sensing principle allows extreme miniaturization of the CO2 sensor without compromising sensor performance due to the fact that the sensor sensitivity is independent of the optical cavity size. The reduced size and the smaller number of integrated components result in a highly price-efficient BOM structure. Thanks to the miniaturizing and the economical BOM structure of these new CO2 sensor, the SCD40 will open up numerous possibilities for a whole new set of products and applications.
