Product description
SCD41-D-R1 – CO₂ Sensor with Extended Measurement Range and Integrated Compensation. The SCD41-D-R1 from Sensirion is an advanced member of the SCD4x family of photoacoustic CO₂ sensors. It builds on the same compact form factor as the SCD40 but offers a wider measurement range, making it particularly suitable for demanding applications in air monitoring, smart buildings, and energy-efficient IoT solutions.
Features:
- CO₂ measurement range: 400–5000 ppm
- Accuracy: ±(40 ppm + 5 % of reading) within 400–5000 ppm
- Integrated sensors: Temperature and relative humidity for automatic compensation
- Operating modes: Continuous measurement or single-shot mode for low-power applications
- Interface: I²C with standard protocol for easy integration
- Supply voltage: 2.4–5.5 V
- Form factor: 10.1 × 10.1 × 6.5 mm
Benefits:
- Extended measurement range up to 5000 ppm for high-CO₂ environments
- Flexible measurement options (continuous or single-shot) optimize energy usage
- Stable performance under varying temperature and humidity conditions
- Compact, reflow-solderable design for volume production
- Factory-calibrated and ready for fast implementation
Typical applications:
- Indoor air quality monitoring and HVAC control with higher measurement requirements
- Smart homes and building automation
- IoT devices and battery-powered systems with a focus on energy efficiency
- Air monitoring in offices, schools, laboratories, and public environments
