 Press Releases

  • Once again, Sensirion trailblazes innovation in environmental sensing to create healthier and more productive envi-ronments for people. At this year’s Sensor+Test 2019 in Nuremberg and SensorsExpo 2019 in San José, the expert in environmental sensing, Sensirion, is announcing the SCD40 – the first miniaturized CO2 and RH/T 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 pos-sibilities. Due to its unprecedented price-performance ratio, the SCD40 is especially well suited for high-volume and cost-sensitive applications.

    Sensirion’s profound expertise in miniaturizing sensors has enabled a breakthrough step in CO2 sensing: with dimensions of just 12 x 12 x 7 mm3, the SCD40 footprint has been miniaturized by a factor of 5 compared to its predecessor, the SCD30. Using the photoacoustic sensing principle, the dimensions of the optical cavity are drastically reduced without compromising on sensor perfor-mance. Moreover, the SCD40 CO2 and RH/T sensor leverages Sensirion’s outstanding environmen-tal sensing expertise by incorporating a best-in-class humidity and temperature sensor that delivers two additional sensor outputs. Because of its unmatched size and its unprecedented price-perfor-mance ratio, the SCD40 is the sensor of choice for today’s and future CO2 sensing markets such as IoT, automotive, HVAC, appliances and consumer goods.

    Thanks to new energy standards and better insulation, buildings have become increasingly energy efficient, but at the cost of accelerated deterioration in air quality. Since high CO2 levels compromise human health and productivity, CO2 is a key indi-cator for indoor air quality. Air exchangers and smart ventilating systems in the commercial and the residential sector use CO2 sensors to regulate ventilation in the most energy-efficient and human-friendly way. Furthermore, CO2 sensors play an essential role for indoor air quality monitoring and can therefore be integrated in IAQ monitors, air purifiers and smart thermo-stats. The SCD40 miniature CO2 and RH/T sensor solution will revolutionize product design approaches and create the foun-dation for a vast array of new applications.

    Visit Sensirion at the Sensor+Test 2019 at booth no. 316 in hall 1 as well as at the SensorsExpo 2019 at booth no. 324 in hall M2 to experience the new sensor solution live in action. Furthermore, there will be an exclusive meeting with a live demonstration for selected customers at both events, offering a deeper insight into the upcoming innovation and its availabil-ity.

  • Sensirion, the worldwide leading manufacturer of high-quality flow and environmental sensors, is launching a new evaluation kit. With the EK-F3x-CAP, expiratory and proximal sensors of the SFM3xxx platform can be tested quickly and easily. The evaluation kit works with both the disposable and reusable variants of the flow sensors.

    The EK-F3x-CAP evaluation kit offers a simple and cost-effective way to test sensors of the SFM3xxx platform. The set consists of a USB cable which connects to the corresponding flow meters. Using the software available online, the sensors can be quickly tested under real-life conditions. There is no need to program a microprocessor as the evaluation kit can be directly connected to a PC. The software shows the measurement data directly on the user's computer screen. Furthermore, the data can be exported into an Excel spreadsheet which can then easily be saved and further processed.

    The Sensirion SFM3xxx platform includes sensors for inspiratory, expiratory and proximal flow measurement, as well as gas mixing in ventilation and anesthesia applications. With the platform, the sensor manufacturer offers its customers the right sensor for all flow measurements and underscores its worldwide expertise in the field of medical ventilation. The reusable "AW" versions are autoclavable and washable, and therefore well-suited for expiratory flow measurement. The disposable "D" versions are a safe and cost-effective alternative to reprocessing.

    Like all sensors from Sensirion, the outstanding performance of the SFM3xxx sensors is based on the patented CMOSens® Technology. This enables integration of the sensor and evaluation circuit on a single CMOS silicon chip. The result is an ultra-precision system that offers long-term stability for sophisticated and cost-sensitive applications. The technology is also highly resistant to environmental effects, which is why Sensirion's flow sensors are perfect for use as sterilizable sensors.
