Sensirion introduces the first miniature CO2 and temperature and humidity sensor

     An expert in the field of environmental sensing, Sensirion the SCD40 - the first miniature CO2 and temperature and humidity sensor with a volume of just 1 cubic centimeter - will be introduced. Based on the principle of photoacoustic sensing, this disruptive and innovative product combines small size and high performance, opening up more possibilities for various integration methods and new application scenarios. The SCD40 offers a higher price/performance ratio and is particularly suitable for high-volume and cost-sensitive applications.

     Sensirion's deep expertise in sensor miniaturization has enabled it to take a breakthrough step in CO2 sensing: the SCD40 measures just 12 x 12 x 7 mm3, a five-fold reduction in size compared to the previous generation SCD30. Using the principle of photoacoustic sensing, the size of the SCD40 optical resonator can be greatly reduced without affecting the performance of the sensor.

     In addition, the SCD40 CO2 and Temperature and humidity sensor leverages Sensirion's extensive environmental sensing expertise with best-in-class temperature and humidity sensors capable of delivering two additional sensor outputs. With its unmatched miniature size and better price/performance ratio, the SCD40 is the first choice in today's and tomorrow's CO2 sensing markets, such as iot, automotive, HVAC systems, appliances and consumer electronics.

     Thanks to new energy standards and better isolation, buildings are becoming more energy efficient, but at the cost of accelerating the deterioration of air quality inside them. Because high levels of carbon dioxide can harm human health and productivity, carbon dioxide levels are a key indicator of indoor air quality. New fans and smart ventilation systems in commercial and residential areas often use carbon dioxide sensors to regulate ventilation in the most energy-efficient and beneficial way for the human body.

     In addition, carbon dioxide sensors also play a vital role in indoor air quality monitoring and can therefore be integrated in indoor air quality monitors, air purifiers and smart thermostats. The SCD40 micro CO2 and temperature and humidity sensor solution will revolutionize product design and lay the foundation for a large number of new applications.
