SGP41 VOC and NOx Sensor
The SGP41 is Sensirion’s new VOC and NOx sensor designed as digital smart switch and regulation unit for air treatment devices such as air purifiers. The two sensor signals processed by Sensirion’s powerful Gas Index Algorithm can be directly used to automatically trigger the removal of indoor air gas pollutants by air treatment devices without the need for user–device interaction. This sensor solution is thus well-suited for constantly monitoring the VOC and NOx situation including potentially harmful events which are not perceived by humans. Furthermore, an automatic control of air treatment devices based on the SGP41 signals helps to save energy by turning them off once the VOC and/or NOx events have been taken care off.

Cable configuration:
Red cable = VDD
Black cable = GND
Green cable = SDA (I2C) or RX (UART)
Yellow cable = SCL (I2C) or TX (UART)
Blue cable = SEL (interface select – connect to GND for I2C, connect to VDD or leave open to select UART)
Purple cable = NC (do not connect)
Evaluation Kit Quick Start
Start evaluating your SGP41 VOC+NOx sensor in two simple steps:
1) Either download the SEK-ControlCenter viewer software (available for Windows, Linux and MacOS) or download one of our example drivers for your embedded platform (see links below). A simple step-by-step quick start guide can be found here.
2) Connect the SVM41 development board to your computer/embedded platform with the help of the adapter and start measuring
