Miniaturized CO₂ sensor for US HVAC applications is now available globally

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.
