Thermal comfort is an important factor in climate control systems. Under which conditions does one feel comfortable, when does one feel discomfort and at what point do conditions impair human health? Relative humidity and temperature play a key role in this context, and thus personal well being can be improved by the use of humidity and temperature sensors.

The widespread use of new products and building materials has resulted in increased concentrations of indoor pollutants, in particular volatile organic compounds (VOCs). Many of these compounds are known to impair well being and productivity; e.g. through headaches, eye irritation or dizziness. Sensirion gas sensor solutions monitor these indoor air pollutants and thus help manufacturers in the development of new smart home and HVAC applications.

PM2.5 and PM10 refer to particulate matter with particle diameter up to 2.5 microns and 10 microns, respectively, and are among the most dangerous air pollutants. Due to their small size, PM2.5 particles can travel deep into the human lung and cause a variety of health issues; for instance, by triggering asthma attacks or contributing to cardiovascular disease. Sensirion’s new PM2.5 sensor solution will enable the implementation of innovative air quality monitoring devices that prevent air pollution damage.

Carbon Dioxide is a key indicator for indoor air quality. Thanks to new energy standards and better insulation, houses have become increasingly energy-efficient, but the air quality can deteriorate rapidly. Active ventilation is needed to maintain a comfortable and healthy indoor environment, and improve the well-being and productivity of the inhabitants. Sensirion sensor solutions offer an accurate and stable monitoring of CO₂ in the air, as well as temperature and humidity. This enables our customers to develop new solutions that increase energy efficiency and simultaneously support the well-being of everyone.

Your health is your greatest asset. In order to enable more people to live longer, healthier and happier lives, Sensirion has developed sensor solutions to improve medical devices and smart home applications such as air purifiers and air cleaners.

Deep down, everyone is looking to increase their quality of life, and Sensirion’s unique, intelligent sensor solutions do just that. As the leading international manufacturer of environmental sensor solutions, we offer our clients sensor solutions for increased convenience and security.

With efficient systems, we have the chance to significantly improve the global energy balance and make a major contribution to environmental protection. Through energy-efficient applications, we can counteract the constantly growing energy consumption around the world and at the same time reduce harmful emissions. That’s why we offer our clients in a wide variety of industries sensor solutions for sustainable and efficient energy management.

With more than 15 years’ experience in the development and supply of environmental sensor solutions, we lead the field in sensor technology innovation. We provide the sensor hardware and support our customers during the design-in, the development of sophisticated algorithms and the industrialization all the way to mass production. In addition to providing unparalleled performance, we also focus on key characteristics such as size, ultra-low power consumption, fully calibrated digital output and compatible supply voltages.

Thanks to our patented CMOSens® Technology, Sensirion was the first company to offer an automotive-grade, digital humidity sensor with a calibrated and linearized signal output. As an innovation-driven company, we did not stop with state-of-the-art humidity sensors, but have continued to develop other sensor types, such as mass flow meters and controllers for gases, differential pressure sensors and liquid flow sensors. We are always keen to find new sensor solutions for demanding applications, which is why our environmental sensor solutions portfolio constantly looks to the future.
