7Semi SGP40 VOC Air Quality Sensor Breakout: Breathe Easy with Confidence
Maintain a Healthy Indoor Environment
The 7Semi SGP40 VOC Air Quality Sensor Breakout offers a powerful solution for monitoring indoor air quality. This compact sensor board integrates the cutting-edge SGP40 sensor, designed to detect a wide range of volatile organic compounds (VOCs) and harmful gases.
Unmatched Accuracy and Ease of Use
The SGP40 sensor is known for its superior accuracy and sensitivity, making it the ideal choice for ensuring optimal indoor air quality. The breakout board boasts a user-friendly I2C interface and compatibility with both 3.3V and 5V power supplies, enabling seamless integration into various projects.
Compact Design, Big Benefits
Measuring just 19 x 19 mm, the 7Semi SGP40 breakout board is perfect for space-constrained environments. Whether you're a DIY enthusiast, an HVAC professional, or simply health-conscious, this sensor provides the tools to take control of your indoor air quality.
Advanced VOC Detection with Sensirion Technology
The SGP40 sensor leverages Sensirion's powerful VOC algorithm to analyze detected VOCs and translate them into a VOC Index. This index offers a practical way to quantify VOC presence relative to the sensor's typical indoor environment. It functions similarly to the human nose, detecting changes in odor and VOCs beyond human perception. The VOC Index effectively indicates improvements or declines in indoor air quality compared to the sensor's baseline.
Benefits of the SGP40 Sensor:
- Exceptional longevity exceeding 10 years
- Pre-programmed VOC Index driver eliminates signal processing needs
- On-chip humidity compensation ensures optimal performance across environments
