Upgraded Sensirion SCD4x CO2 Sensors Available Through Symmetry Electronics

Los Angeles, CA (April 17, 2024)Sensirion, a global supplier of next-generation sensor solutions, has unveiled both the SCD40 and SCD41, an exciting upgrade to its SCD4x family, a line of highly accurate, reliable carbon dioxide (CO2) and humidity sensor modules. Replacing the now obsolete end-of-life (EOL) SCD42, developers can benefit from enhanced specifications, improved performance, and ease of integration offering greater flexibility for precision environmental monitoring design applications.

Sensirion's SCD40 has received several new feature upgrades to enhance its performance and convenience offering precise CO2 measurements with an accuracy of ±(30 ppm + 3% of reading), whereas the SCD41 provides accuracy of ±(20 ppm + 5% of reading). Moreover, the SCD41 features an extended measurement range of up to 40,000 parts per million (ppm) of CO2, while the SCD40 has a range of up to 10,000 ppm. By pushing the boundaries of what is possible, Sensirion continues to demonstrate its commitment to advancing sensor technology and empowering industries to make data-driven decisions. The SCD4x family upgrade is a testament to their dedication, and we can expect more groundbreaking developments from Sensirion in the future.
