The digital gas sensor SGP opens up new possibilities for, inter alia, the measurement of indoor air quality. The long-term stable metal-oxide gas sensor features multiple sensing elements on one chip, the SGP provides in-depth information on air quality. The sensing element features an unmatched robustness against contaminating gases present in real-world applications, enabling a unique long-term stability and low drift. The small package size (2.45 x 2.45 x 0.9 mm3 DFN), the I2C interface, and the dust and water protection membrane make the SGP easy to integrate into a large variety of applications, e.g. in appliances or smart home devices.

Particulate Matter Sensor (Upcoming Technology)

Sensirion’s forthcoming PM2.5 sensor will define new market standards for accurate and reliable detection of PM2.5 and PM10.

With this new particulate matter sensor, Sensirion expands its range of environmental sensing solutions and opens up a new dimension in indoor and outdoor air quality 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.

SDP800 Series – Proven and Improved

The differential pressure sensors of the SDP800 series are the reliable and cost-effective solution for precise air flow measurements in HVAC applications. The sensors are the result of more than 15 years of experience in measuring air flow to millions of HVAC systems, car engines and patients. They consequently utilize the successful features of the SDP600 differential pressure sensor and come in the same proven housing, which enables easy integration. The next generation chip combines outstanding accuracy and long-term stability with extended functionality and higher measurement speed for even lower costs.
