Environmental conditions have a major impact on our well-being, comfort, and productivity. Sensirion’s sensor solutions provide detailed and reliable data on key environmental parameters such as humidity, temperature, volatile organic compounds (VOCs), particulate matter (PM2.5), and CO2. Environmental Sensing opens up new possibilities to create smarter devices that improve our comfort and well-being as well as increase energy efficiency in a wide variety of applications.
SGP40 is Sensirion’s new digital VOC (volatile organic compounds) sensor designed for easy integration into air treatment devices and air quality monitors. Based on Sensirion’s CMOSens® Technology, the SGP40 offers a complete sensor system on a single chip and features a digital I2C interface, a temperature-controlled micro-hotplate and a humidity-compensated indoor air quality signal. In combination with Sensirion’s powerful VOC Algorithm, the sensor signal can be directly used to evaluate indoor air quality, e.g., for triggering the gradual fan control of an air treatment device. Both the SGP40 chip and VOC algorithm feature unrivalled robustness in the final application over their lifetimes.
The STC31 is a chip-sized gas concentration sensor for high range, accurate CO2 measurements designed for high-volume production. The sensor is based on a revolutionized thermal conductivity measurement principle, which results in superior repeatability and long-term stability. This makes the STC31 the perfect choice for applications where reliability is key. Thermal conductivity technology has an ultra-low power consumption, even compared to low-power optical sensor. This makes it the ideal choice for battery operated applications, delivering top-performance at an absolute minimal power budget.
Key Environmental Parameters
Ambient Humidity and Temperature
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.
Volatile Organic Compounds (VOCs)
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.
Particulate Matter (PM2.5)
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.
