The SCD40 CO2, Temperature and Humidity Sensor Breakout Board is engineered for professionals and developers seeking reliable, real-time atmospheric monitoring in a small, efficient package. Leveraging Sensirion’s photoacoustic sensing technology, this sensor ensures superior accuracy within the critical 400–2000 ppm CO2 range, making it a trusted choice for applications requiring precision air quality data. With its fully integrated temperature and humidity sensors, it offers complete environmental insights in a single, compact unit.

Ideal for integration into IoT devices, HVAC systems, smart homes, air quality monitoring stations, and energy-efficient building controls, the SCD40 breakout board supports a wide detection range up to 40000 ppm. Its I2C interface guarantees simple integration with various microcontrollers, while ultra-low power consumption (as low as 0.5 mA) ensures it fits seamlessly into battery-powered and remote systems. Built with longevity in mind, the sensor maintains consistent performance for years with minimal recalibration needs.

Key Features

  • Advanced Photoacoustic CO2 Sensing: Utilises state-of-the-art photoacoustic infrared technology for highly accurate and stable CO2 measurement.

  • Integrated Environmental Sensors: Measures temperature and humidity alongside CO2 levels for a comprehensive atmospheric profile.

  • Wide Measurement Range: Accurately detects CO2 concentrations from 400 ppm up to 40000 ppm; highly precise in the 400–2000 ppm band.

  • Exceptional Accuracy: ±(40 ppm + 5%) ensures dependable readings for mission-critical applications.

  • Energy Efficient Design: Consumes only 17 mA at 5-second intervals or just 0.5 mA at 5-minute intervals, ideal for low-power applications.

  • Fully Calibrated and Ready-to-Use: No additional calibration required, enabling immediate integration and deployment.

  • I2C Communication Protocol: Seamless connectivity with Arduino, Raspberry Pi, ESP32, STM32, and other development boards.

  • Compact and Durable Build: Suitable for integration into space-constrained or embedded systems with long operational life.
