Cutting the size barrier in CO2 sensing with evaluation kit

16-02-2021 | Sensirion | Design & Manufacture

Sensirion now offers the SEK-SCD41 CO2 sensor evaluation kit. The kit has been created for easy and cost-efficient evaluation of the company's SCD4x CO2 sensor.


The device is the company's next-generation miniature CO2 sensor series offering an excellent price-to-performance ratio. The sensor is created on the photoacoustic sensing principle and the company's patented PASens and CMOSens technology to provide a small sensor size coupled with high performance. SMD compatibility and the small footprint allow cost and space-effective integration to increase freedom of design for customers. The integrated humidity and temperature sensor deliver superior on-chip signal compensation and extra RH and T outputs. Finally, the large supply voltage range (2.4-5.5V), the robustness to external stresses and the adjustable power consumption makes the device an excellent fit for varying customer needs.


“Our disruptive SCD4x makes CO2 sensing accessible for new applications and enables customers to use novel design-approaches. The SEK-SCD41 evaluation kit represents the perfect tool kit for effective SCD4x sensor evaluation and efficient prototyping”, says Marco Gysel, product manager CO2 Sensors at Sensirion.


The evaluation kit comprises an SCD41 CO2 sensor mounted on a development board with a JST connector and through-hole pins. The included adapter cable (JST-Ethernet) connects to the SEK-SensorBridge for easy evaluation of the sensor via the SEK-ControlCenter viewer software. Finally, the kit contains a four-pin jumper wire cable that enables fast prototyping, e.g. through integration into existing platforms (such as Arduino, Raspberry Pi and so on).
