Sensirion have launched the SCD4x series of next generation miniature CO2 sensors. The company says that they offer an unmatched price-to-performance ratio.

The sensor and an evaluation kit, SEK-SCD41, which helps developers accelerate their designs are available at Anglia Components.

This sensor builds on the photoacoustic sensing principle and Sensirion’s patented PASense and CMOSense Technology to enable small sensor size combined with high performance.

The SCD4x miniature CO2 sensors are compatible with SMD soldering processes and feature a small footprint allowing cost and space-effective integration to boost freedom of design for customers.

The CO2 sensor also integrates a humidity and temperature sensor which enables on-chip signal compensation and addition RH and Temperature outputs.
