SCD41-D-R2
Overview
The SCD41-D-R2 is a high-accuracy carbon dioxide, humidity, and temperature sensor based on Sensirion PASens photoacoustic technology. It achieves a wide CO2 measurement range of 0 to 40,000 ppm within a compact 10.1mm x 10.1mm x 6.5mm LGA package. The device operates on a supply voltage between 2.4V and 5.5V and provides a digital I2C interface for easy integration into embedded systems.
Why Choose This Part
The photoacoustic measurement principle allows for a significant reduction in sensor size without compromising sensitivity or accuracy. It features a single-shot measurement mode that drastically reduces average current consumption for battery-powered IoT applications. Integrated on-chip signal compensation and CMOSens technology ensure stable long-term operation and reliable environmental data.
Applications
Key Specifications
Getting Started
To begin development, connect the SCD41 to an I2C bus with appropriate pull-up resistors and ensure the supply voltage is within the 2.4V to 5.5V range. Sensirion provides comprehensive C and Arduino libraries to interface with the sensor's 16-bit registers. For rapid prototyping, engineers often use the SEK-SCD41-Sensor evaluation kit or the SCD4x Breakout Board.
