7Semi SGP41 VOC and NOx Sensor Breakout for Indoor Air Quality 2.54mm Pitch

The 7Semi SGP41 VOC & NOx Air Quality Sensor Breakout integrates Sensirion’s SGP41 sensor for indoor air-quality monitoring. It uses MOx gas-sensing technology to monitor both VOC- and NOx-related air-quality changes and communicates through a digital I²C interface. The sensor can be used with Sensirion’s Gas Index Algorithm to generate VOC Index and NOx Index values, making air-quality changes easier to interpret. Its compact breakout design makes it suitable for air purifiers, ventilation systems, smart-home devices, and environmental monitoring applications.

Key Features

• VOC & NOx Monitoring: Detects VOC- and NOx-related changes in indoor air quality using separate sensing channels.
• VOC & NOx Index: Supports processed VOC Index and NOx Index outputs from 1 to 500.
• Digital I²C Interface: Supports simple digital communication with microcontrollers and embedded systems.
• Humidity Compensation: External temperature and humidity data can be supplied to improve gas-sensing consistency.
• Long-Term Stability: Designed for stable performance in real-world indoor air-quality applications.
• Compact Breakout Design: Easy to integrate into space-constrained prototypes and finished products.
