Sensirion SEK-SCD41 CO2 Sensor Evaluation Kit

Sensirion SEK-SCD41 CO2 Sensor Evaluation Kit enables easy plug and play evaluation of the miniaturized SCD4x sensors and facilitates prototyping. Electrical interfacing can be realized either via the through-hole pads or alternatively via the included jumper cable that connects to the integrated JST connector. The compact design measuring 28mm x 24mm x 8mm, the large supply voltage range (2.4V to 5.5V), and the mounting holes allow versatile prototyping.

The SCD4x Miniature CO2 sensors build on the photoacoustic sensing principle and Sensirion’s patented PASens® and CMOSens® technology to offer high accuracy at an unmatched price in a small form factor. SMD assembly allows cost- and space-effective integration of the sensor combined with maximal freedom of design.
