With dimensions of just 10,1 x 10,1 x 6,5 mm, the SCD40 from Sensirion’s footprint has been miniaturised by a factor of five compared to its predecessor, the SCD30. Using the photoacoustic sensing principle, the dimensions of the optical cavity are drastically reduced without compromising sensor performance.
Moreover, the SCD40 CO2 and RH/T sensor incorporates a high-quality humidity and temperature sensor that delivers two additional sensor outputs. Its features make it highly suitable for 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. Air exchangers and smart ventilating systems in the commercial and residential sectors use CO2 sensors to regulate ventilation in the most energy-efficient and human-friendly way. Furthermore, CO2 sensors play an essential role in indoor air quality monitoring and can, therefore, be integrated into IAQ monitors, air purifiers, and smart thermostats.
