The Sensirion SGP41 is a digital MOx based gas sensor for measuring VOX and NOx. Sensirion’s CMOSens® technology offers a complete sensor system on a single chip featuring a digital I2C interface and temperature-controlled micro hotplates. Providing you with a VOC (volatile organic compound) and a NOx (nitrogen oxides) based indoor air quality signal.
The sensing element and gas Index algorithm feature robustness against contaminating gases that are present in real-world applications, supporting long-term stability as well as low drift. The Sensirion SGP41 comes in a small DFN package, great for applications where space is limited. The air quality sensor has low power consumption. Applications include air purifiers, air quality monitoring and demand-controlled ventilation systems.
Evaluation kit SEK-SVM4x for SGP40/41 is also available, see RS 234-8989 the kit contains an SVM development board equipped with the 1 x SGP41, 1 x SHT40. 1 x UART to USB adapter cable, jumper wire cable set.
Recommended operating conditions 0 to 90 %RH, -10 to +50 °C Supply voltage 1.7 to 3.6 V DFN 6-pin package 2.44 x 2.44 x 0.85 mm3 Device to device variation VOC ±15 VOC Index points or % (the larger) Device to device variation NOx ±50 NOx Index points or % (the larger)
Notes
For VOC and NOx Index outputs customers need to integrate the Gas Index Algorithm (available on github) on their microcontroller.
For products that are Customized and under Non-cancellable & Non-returnable, Sales & Conditions apply.
