• New versions of the SEN5x environmental sensor node now available (May 02, 2022)

  Sensirion presents its SEN50 and SEN55 environmental sensing solutions for measuring relevant environmental parameters. The SEN50 and SEN55 environmental sensor nodes serve as a straightforward sensor solution platform whose simple integration can reduce time-to-market and cut costs for manufacturers of indoor air quality solutions.

  Stäfa, Switzerland – April 2022 – Indoor air pollution inside buildings such as workplaces or homes can be harmful to breathe in and can lead to long-term health issues. Air pollution in enclosed spaces not only comes from outside air but can also be released by sources such as cleaning products and cooking. It is therefore important to maintain good indoor air quality in order to have a healthy and safe environment. Inadequate ventilation and a lack of air purification can lead to higher levels of indoor pollutants. Monitoring environmental parameters can help to indicate when ventilation or air purification is necessary by reporting the levels of relevant pollutants.

  Sensirion’s environmental sensor nodes are designed for use in indoor air quality applications. The SEN50 environmental node is part of the SEN5x series and represents a straightforward sensor solution platform for the accurate measurement of particulate matter. In addition to particulate matter, the SEN55 is able to detect other environmental parameters, such as volatile organic compounds (VOCs) and oxidizing gases (NOx), as well as humidity and temperature. Sensirion’s algorithms enable straightforward integration into various applications. The implemented engine known as Sensirion Temperature Acceleration Routine (STAR) accelerates the device’s response to ambient temperature changes by a factor of two to three. This, together with a temperature compensation engine, provides a better user experience and more accurate measurements to end-users. Device manufacturers therefore save valuable project time and personnel resources. End customers receive reliable air quality measurement and can benefit from an improved indoor environment with better health and comfort. 

  “Built on highly reliable and advanced environmental sensors, Sensirion has developed the SEN5x environmental sensor node to provide a fast and straightforward integration into indoor air quality applications. With the SEN50 and SEN55, we offer new versions to fulfill our customers’ needs and continue our efforts to lead the journey in environmental sensing solutions,” says Antonio Rubino, Environmental Sensor Node Product Manager at Sensirion.

• Miniaturized CO2 sensor for US HVAC applications (May 02, 2022)

  Sensirion, the expert in environmental sensing, has launched a new product in its SCD4x miniaturized CO2 sensor series. The SCD42 has been designed for products that fall under California’s Building Energy Efficiency Standards (Title 24), and is therefore perfectly suited for US HVAC applications. The sensor is now available worldwide through Sensirion’s distribution network.

  High levels of carbon dioxide (CO2) compromise humans’ cognitive performance and well-being. Thanks to new energy standards and better insulation, houses have become increasingly energy efficient. However, CO2 produced by human metabolism can accumulate rapidly indoors. Therefore, CO2 is a key indicator for indoor air quality. Measuring indoor CO2 concentration enables smart ventilation systems to regulate ventilation in the most energy-efficient and people-friendly way. Moreover, indoor air quality monitors and other connected devices can help to maintain a low CO2 concentration for a healthy, productive environment.

  The SCD42 is Sensirion’s newest addition to the SCD4x product line. Specifically designed for products that fall under California’s Building Energy Efficiency Standards (Title 24), the SCD42 offers unmatched cost effectiveness for the US HVAC market. This disruptive innovation is based on the principle of photoacoustic sensing and combines minimum size with maximum performance to open up numerous new possibilities for integration and application. The SCD42 offers an accuracy of ±75 ppm at 400–1000 ppm. SMD compatibility and its small footprint allow cost-effective and space-saving integration to increase device manufacturer’s freedom of design. This integrated, best-in-class humidity and temperature sensor enables superior on-chip signal compensation and additional RH and T outputs. Finally, the large supply voltage range (2.4–5.5 V) and the robust resistance to external stresses make the SCD42 the perfect fit for all kinds of customer needs.

  “Smart building ventilation systems leverage a CO2 sensor to optimize indoor air quality while keeping energy consumption at a minimum. Thanks to its compact size and easy assembly, the SCD42 lowers the hurdle for integrating a CO2 sensor into ventilation systems. I am excited that the SCD42 will help boost people’s well-being and reduce our buildings’ carbon footprint,” says Marco Gysel, CO2 Sensors Product Manager at Sensirion.

  The SCD42 sensor is available worldwide through Sensirion’s distribution network. Learn more about the SCD42 CO2 sensor at www.sensirion.com/scd4x

• VOC+NOx sensor for indoor air quality applications (May 02, 2022)

  Sensirion, the expert in environmental sensing, presents the SGP41 VOC+NOx sensor for indoor air quality applications. The sensor is designed as a digital smart switch and regulation unit for air treatment devices such as air purifiers.

  Good air quality is an important component of a healthy indoor environment because indoor air pollution can have harmful impacts on our health. There are many potential and common dangers found in indoor air, such as VOCs (volatile organic compounds), which are typically found in building materials, furniture and cleaning products, among others, and are emitted by humans, and NOx (nitrogen oxides), which are a by-product of combustion. Exposure to these pollutants can be limited by ensuring that enclosed spaces have sufficient ventilation. In addition, air treatment devices are used to eliminate harmful gases in indoor environments and thus avoid unhealthy situations. Equipped with Sensirion’s new SGP41, air purifiers become smart by reliably monitoring VOCs and NOx at all times and removing these gas emissions automatically when the appropriate filters are installed.

  The VOC+NOx sensor offers a solution for two complete sensors on a single chip, facilitating design-in and cutting design costs. By relying on Sensirion’s proven MOXSens® Technology, the sensor’s unmatched robustness against contamination by siloxanes results in outstanding long-term stability in terms of sensitivity and response time. The two sensor signals processed by Sensirion’s powerful Gas Index Algorithm can be used directly to automatically trigger the removal of indoor air gas pollutants by air treatment devices without the need for user-device interaction. This sensor solution is thus well-suited to the constant monitoring of VOC and NOx levels, including potentially harmful events that are imperceptible to humans. Furthermore, automatic control of air treatment devices based on the SGP41’s signals helps to save energy by turning them off once the VOC and/or NOx events have been taken care of.

  “This sensor platform enables the simultaneous measurement of both volatile organic compounds and nitrogen oxides, and therefore responds to the growing awareness of the importance of good indoor air quality and the stricter requirements for these applications. With the SGP41, Sensirion aims to further improve indoor air quality and help to protect our health and well-being,” says Dr. Oliver Martin, Product Manager for Gas Sensors at Sensirion.

  Both SGP41 and the evaluation kit are available worldwide through Sensirion’s distribution network.
