The 7Semi SCD41 CO₂ Sensor Breakout is a compact, high-performance environmental sensing module designed for precise carbon dioxide monitoring in advanced applications. Built around Sensirion’s cutting-edge photoacoustic sensing technology, it delivers highly accurate and stable CO₂ measurements with minimal power consumption.
In addition to CO₂ sensing, the module integrates temperature and humidity sensors, enabling real-time environmental compensation for improved measurement accuracy. With a digital I²C interface and factory calibration, the SCD41 breakout ensures seamless integration and immediate deployment in embedded systems, IoT devices, and industrial applications.
Its ultra-low power operation and small footprint make it ideal for both portable and fixed installations, including smart air quality systems, HVAC automation, and environmental monitoring platforms.
