Arrow Electronics and Trenz Electronic developed a very small and comprehensive module for qualified CO2 measurements to support customers in their development and end products.
The CRUVI module (32 mm x 18 mm) includes Sensirion's new SCD40 miniature CO2 sensor. The SCD4x family has also an integrated humidity sensor and temperature sensor. To create full solutions with the CRUVI module and use it for condition monitoring applications, it also has an ambient light sensor and an ambient pressure sensor. For indication of a status or critical CO2 levels, an RGB LED can send out warning signals and a buzzer mounted on the bottom side of the module can generate acoustic signals.

The new CO2 sensor is based on the photoacoustic sensor principle and the patented Sensirion technologies PASens® and CMOSens®, providing maximum performance in addition to minimum size. SMD compatibility and extremely compact dimensions enable cost-efficient and space-saving integration of customer designs. The integrated, industry-leading humidity and temperature sensor provides excellent on-chip signal compensation as well as additional RH and T outputs. With its large voltage range of 2.4 to 5.5V, insensitivity to external loads and adjustable power consumption, the SCD40 is ideal for a wide variety of customer requirements.

In order to achieve good measurement results, the DesignIn Guide from Sensirion should be observed.
