The SEK-SGP4x-Sensor evaluation kit is designed for engineers and developers to quickly prototype and integrate Sensirion’s VOC and NOx gas sensors into their applications. It supports both SGP40 and SGP41 sensor operation modes and includes a combined humidity and temperature sensor SHT41. Unlike the SEK-SVM4x evaluation kit, this breakout board has no onboard microcontroller and outputs only raw sensor values (SRAW). To obtain VOC and NOx Index or other processed signals, the SEK-SGP4x board can be connected to PC using Sensirion’s SEK-SensorBridge and read out with the SEK-ControlCenter software.
