Renowned for its precision and sensitivity, the SGP40 stands as the benchmark in VOC sensors, making it the ideal selection for individuals aiming to ensure the utmost safety and healthiness of their indoor air.

Featuring a user-friendly I2C interface and compatibility with both 3.3V and 5V power sources, the 7Semi SGP40 VOC Air Quality Sensor Breakout exhibits remarkable versatility and effortless integration into any project. With its compact dimensions measuring just 19 x 19mm, it seamlessly fits into even the most confined spaces.

Whether you're an avid DIY enthusiast, a seasoned HVAC professional, or simply someone aspiring to inhale pure air, the 7Semi SGP40 VOC Air Quality Sensor Breakout stands as the optimal preference. Settle for nothing but excellence – employ the 7Semi SGP40 VOC Air Quality Sensor Breakout today and witness the transformative impact firsthand!

Sensirion's potent VOC Algorithm (an integral part of the SGP40 VOC Index driver package) scrutinizes VOC events identified by the SGP40 sensor, translating them into a VOC Index. This index offers a practical quantification of VOC events concerning each sensor's typical indoor setting. Functioning akin to the human nose, which is highly responsive to changes in scent, the VOC Index also detects events that elude human perception. It signifies the extent to which indoor air quality has either degraded or improved compared to the sensor's standard VOC environment.
