Miniaturized CO2 Sensor from Sensirion
Sensirion’s 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 performance. Applications are CO2 sensing for 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 indicator 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 thermostats. The SCD40 miniature CO2 and RH/T sensor solution will revolutionize product design approaches and create the foundation for a vast array of new applications.
