The GY-SGP41 Air Quality Sensor Module is a high-performance digital gas sensor designed for indoor air quality monitoring. Built around the Sensirion SGP41, it detects VOC- and NOx-related gas signals and, when used with Sensirion's Gas Index Algorithm, provides VOC Index and NOx Index outputs for intelligent air quality assessment.
The module communicates via an I²C interface, allowing easy integration with embedded systems and development boards. Its compact design, low power consumption, and long-term stability make it suitable for smart homes, HVAC systems, office automation, industrial monitoring, and portable air quality devices.
Features :
- Based on the high-precision Sensirion SGP41 gas sensor.
- Detects VOC- and NOx-related gas signals for indoor air quality monitoring.
- Supports I²C digital communication for easy microcontroller integration.
- Low power consumption suitable for battery-powered IoT devices.
- Compatible with Arduino, ESP32, STM32, Raspberry Pi, and other I²C-enabled platforms.
- Supports Sensirion's Gas Index Algorithm for VOC Index and NOx Index calculations.
