Yoetaun SCD30 CO2 Sensor Module Black 3.5 x 2.3cm

HVAC and indoor air quality sensor

The Yoetaun SCD30 module measures absolute carbon dioxide concentration alongside relative humidity and temperature. It is designed for HVAC systems and indoor air quality monitoring where reliable long-term readings are required. The dual-channel principle compensates for sensor drift to maintain stability over time.

Compact module for custom monitoring builds

At approximately 3.5 x 2.3cm the board fits inside tight enclosures and prototype housings. It delivers three sensor signals through Sensirion CMOSense technology without needing separate temperature or humidity sensors. Builders must provide their own power supply, communication interface and data-logging software.

Single sensor board in the package

The box contains one CO2 sensor module and no cables, headers or mounting hardware. Users add connectors or solder directly to the pads to integrate the module into a microcontroller or single-board computer. No calibration kit or configuration utility is included.
