Breaking the size barrier in CO2 sensing: SCD4x Evaluation Kit available now

Sensirion AG presents the SEK-SCD41 CO₂ sensor evaluation kit, which has been designed for easy and cost-efficient evaluation of Sensirion’s SCD4x CO₂ sensor.

Measurement of CO₂ concentration for intelligent ventilation concepts

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 the human metabolism can accumulate rapidly. 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 human-friendly way. Moreover, indoor air quality monitors and other connected devices can help to maintain a low CO₂ concentration for a healthy, productive environment.

Small sensor size combined with high performance enables cost- and space-saving integration

The SCD4x is Sensirion’s next-generation miniature CO₂ sensor series. The sensor is built on the photoacoustic sensing principle and Sensirion’s patented PASens and CMOSens Technology to enable unmatched small sensor size combined with high performance. SMD compatibility and the small footprint allow cost- and space-effective integration to boost freedom of design for customers. The 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 V – 5.5 V), the robustness to external stresses and the adjustable power consumption make the SCD4x the suitable for varying customer needs.

The evaluation kit contains a SCD41 CO₂ sensor mounted on a development board with a JST connector and through-hole pins. The included adapter cable (JST-Ethernet) connects to Sensirion’s SEK-SensorBridge for easy evaluation of the sensor via the SEK-ControlCenter viewer software. Finally, the kit contains a 4-pin jumper wire cable that enables fast prototyping, e.g. through integration into existing platforms (like Arduino, Raspberry Pi and so on). Start evaluating the SCD4x CO₂ sensor; the kit is now available worldwide through Sensirion’s distribution network. The SCD40 and SCD41 sensor components will be available soon.
