SGP41-D-R4 Gases Detected, Sensirion SGP41-D-R4, Ethanol, Nitrogen Dioxide Air Quality Sensor for Air Quality Monitors

The Sensirion digital gas sensor is designed for easy integration into air purifiers or demand controlled ventilation systems. The technology it offers is a complete , easy to use sensor system on a single chip featuring a digital I²C interface and temperature controlled micro hotplates, providing one VOC and one NO x based indoor air quality signal.Both sensing element and Gas Index Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift. The very small DFN package enables applications in limited spaces. The state of the art production process guarantees high reproducibility and reliability. Tape and reel packaging together with suitability for standard SMD a assembly processes make the sensor predestined for high volume applications.

Notes
For VOC and NOx Index outputs customers need to integrate the Gas Index Algorithm (available on github) on their MCU
