Description

The 7Semi SCD41 Breakout Mini integrates Sensirion’s SCD41 sensor, which employs Photoacoustic NDIR (Non-Dispersive Infrared) sensing technology for precise COâ‚‚ detection alongside integrated digital sensors for temperature and relative humidity. The module provides stable, calibrated readings directly via its I2C serial bus.

Designed for continuous monitoring applications, the board features a wide operating voltage and low power consumption, making it suitable for battery-powered IoT devices. Its compact form factor and pre-calibrated output simplify integration into environmental control systems, portable monitors, and embedded projects requiring reliable multi-parameter data.

Key Features

  • High-precision NDIR-based COâ‚‚ sensing from 400 to 5000 ppm.
  • Simultaneous digital output for temperature and relative humidity.
  • Factory calibration ensures long-term measurement stability and accuracy.
  • Wide 2.4V to 5.5V DC supply range compatible with 3.3V and 5V logic families.
  • Low power consumption optimized for battery-operated and portable applications.
  • Compact 20mm x 20mm breakout board with standard 0.1" pin spacing.
  • Robust I2C digital interface for reliable communication with host controllers.
  • High-value build for indoor air quality monitoring and HVAC system integration.

Applications

  • Indoor air quality (IAQ) monitoring and demand-controlled ventilation (DCV) systems.
  • Smart HVAC control and energy management in commercial and residential buildings.
  • Portable environmental data loggers and IoT sensor nodes for green building analytics.
  • Classroom and office air quality assessment to ensure healthy COâ‚‚ levels.

Frequently Asked Questions

What is the operating voltage range for the SCD41 breakout module?

The module operates from 2.4V to 5.5V DC, making it compatible with both 3.3V and 5V microcontroller systems like Arduino Uno, ESP32, and Raspberry Pi. Ensure your power supply is stable within this range for accurate sensor readings.

How do I communicate with this sensor? What is the pinout?

Communication is via the I2C serial interface. The standard breakout pins are VCC, GND, SCL (serial clock), and SDA (serial data). You will need to connect these to the corresponding I2C pins on your host controller and use the appropriate Sensirion SCD4x library to read the COâ‚‚, temperature, and humidity data.

Is the sensor pre-calibrated, or does it require manual calibration?

The SCD41 sensor is factory calibrated, so no user calibration is required for standard operation. It provides accurate readings immediately upon power-up. For applications requiring traceable accuracy, periodic verification against a reference may be recommended.

What is the measurement update rate for COâ‚‚, temperature, and humidity?

The SCD41 sensor typically provides a new measurement set approximately every 5 seconds. The integrated sensor performs a full measurement cycle internally, and the data is available for reading via I2C commands at this interval.

Can this sensor be used for outdoor air quality monitoring?

While primarily designed for indoor applications, it can be used outdoors if properly housed in a weatherproof enclosure that protects it from direct rain and condensation. Note that the COâ‚‚ measurement range (up to 5000 ppm) is suitable for indoor and many outdoor environments, but extreme conditions may affect long-term stability.
