CO2 sensor for US HVAC applications is now available globally

Sensirion 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 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 (more info).
