Sensirion Holding AG announced that it has launched a new product in its SCD4x miniaturized CO2 sensor series. 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 plus or minus 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. The SCD42 sensor is available worldwide through the company’s distribution network.
